+
+## 2026-01-01 - 3.24.0 - feat(workspace)
+add workspace bottom bar, terminal tab manager, and run-process integration
+
+- Add dees-workspace-bottombar component and export; bottom bar emits run-process events to launch processes.
+- Introduce terminal interfaces (IRunProcessEventDetail, ITerminalTab, ICreateTerminalTabOptions, etc.) and a TerminalTabManager to manage multiple terminal tabs and lifecycle.
+- Integrate bottombar into dees-workspace: layout refactor (workspace-outer), move/adjust resize handles and panels, and handle @run-process to create terminal tabs and focus terminal panel.
+- Enhance dees-workspace-terminal: tabbed terminal UI, new public APIs (createProcessTab, writeToTab, sendInputToTab), theme updates, and improved disposal/cleanup behavior.
+- Update module exports to include bottombar and additional terminal sub-exports (interfaces, terminal-tab-manager).
+
+## 2025-12-31 - 3.23.0 - feat(workspace)
+add resizable file tree and terminal panes with draggable handles and public layout APIs
+
+- Introduce reactive state for currentFileTreeWidth, currentTerminalHeight, isDraggingFileTree and isDraggingTerminal

+- Expose public layout methods: setFileTreeWidth, setTerminalHeight, resetLayout
+
+## 2025-12-31 - 3.22.0 - feat(workspace)
+add resizable markdown editor/preview split with draggable handle and markdown outlet styling/demo
+
+- Introduce a flexible split layout for the workspace markdown editor with a draggable resize handle (splitRatio, minPanelSize, dragging state, mouse handlers and cleanup).
+- Enhance dees-workspace-markdown: switch from grid to flex, add resize handle UI, prevent pointer selection while dragging, notify Monaco on resize.
+- Add comprehensive styling and demo content for dees-workspace-markdownoutlet (dark/light themed markdown styles, syntax highlighting classes, and demo scenarios).
+- Fix typescript-intellisense monaco model update: only set model value when content actually changed to avoid cursor resets.
+- Add markdown outlet demo helper and numerous screenshot/image assets (.playwright-mcp) for demos/documentation.
+
+## 2025-12-31 - 3.21.0 - feat(terminal)
+add dynamic bright/dark theming for terminal components and terminal preview
+
+- Add bright/dark theme PNG assets under .playwright-mcp for previews.
+- Replace hardcoded terminal background/colors with cssManager.bdTheme in workspace terminal and preview styles.
+- Introduce getTerminalTheme helper to compute xterm theme for bright/dark modes.
+- Subscribe to themeManager.themeObservable and apply updates to xterm (terminal.options.theme) so terminals update live on theme change.
+- Remove hardcoded background property/CSS var and unused background accessor from workspace terminal.
+- Ensure proper cleanup: unsubscribe theme subscriptions and dispose terminals in disconnectedCallback.
+
+## 2025-12-31 - 3.20.1 - fix(dees-workspace)
+fix demo wrapper and workspace layout; always render terminal preview
+
+- Import @design.estate/dees-wcctools/demotools and wrap demo content in <dees-demowrapper>
+- Create an absolute-positioned container so the dees-workspace fills 100% height/width
+- Always render dees-workspace-terminal-preview (use empty command when none) to avoid conditional rendering issues
+- Set a fixed height (200px) for the terminal preview in the initializing state
+- Add Playwright demo asset .playwright-mcp/dees-workspace-demo-4k.png
+
+## 2025-12-31 - 3.20.0 - feat(workspace)
+rename editor components to workspace group and move terminal & TypeScript intellisense into workspace
+
+- Renamed components and modules from 00group-editor/dees-editor-* to 00group-workspace/dees-workspace-* (e.g. dees-editor-monaco -> dees-workspace-monaco).
+- Moved terminal implementation from dees-terminal to dees-workspace-terminal and updated related imports/usages.
+- Moved TypeScript intellisense manager into 00group-workspace and updated paths.
+- Updated ts_web elements index to export 00group-workspace instead of 00group-editor and adjusted internal imports accordingly.
+- Updated scripts/update-monaco-version.cjs to write MONACO_VERSION into the new workspace path and updated log tags.
+
+## 2025-12-31 - 3.19.1 - fix(intellisense)
+Debounce TypeScript/JavaScript IntelliSense processing and cache missing packages to reduce work and noisy logs
+
+- Add 500ms debounce in editor workspace to avoid parsing on every keystroke
+- Introduce notFoundPackages cache to skip repeated filesystem checks for packages without types
+- Clear not-found cache when scanning node_modules so newly installed packages are re-detected
+- Remove noisy console logs and make file/directory read errors non-fatal (ignored)
+- Simplify processContentChange signature (removed optional filePath) and remove manual diagnostic refresh logic
+
+## 2025-12-31 - 3.19.0 - feat(dees-editor-workspace)
+improve TypeScript IntelliSense, auto-run workspace init commands, and watch node_modules for new packages
+
+- Execute an onInit command from /npmextra.json on workspace initialization (e.g., run pnpm install).
+- Add npmextra.json and an import test file (importtest.ts) plus a sample dependency in the scaffold to test package imports.
+- Add node_modules watcher with debounce to auto-scan and load package types after installs.
+- Enhance TypeScript IntelliSense: recursively load all .d.ts files from packages and @types packages, add package.json as extra lib, and log progress/errors for debugging.
+- Change processContentChange signature to accept optional filePath and trigger a diagnostic refresh when new types are loaded.
+- Expose scanAndLoadNewPackageTypes to scan top-level and scoped packages and load their types.
+- Add start/stop logic for the node_modules watcher in workspace lifecycle to avoid leaks and handle cleanup.
+
+## 2025-12-31 - 3.18.0 - feat(filetree)
+add filesystem watch support to WebContainer environment and auto-refresh file tree; improve icon handling and context menu behavior
+
+- Add IFileWatcher interface and watch(...) signature to IExecutionEnvironment.
+- Implement watch(...) in WebContainerEnvironment using WebContainer's fs.watch and return a stop() handle.
+- dees-editor-filetree: start/stop file watcher, debounce auto-refresh on FS changes, cleanup on disconnect, and track last execution environment.
+- Add clipboard state (copy/cut) and related UI/menu enhancements for file operations (new file/folder, rename, delete, copy/paste).
+- dees-icon: default to Lucide icons when no prefix is provided.
+- dees-contextmenu: remove 'lucide:' prefix usage in templates and avoid awaiting windowLayer.destroy() to provide instant visual feedback.
+- Menu item shape adjusted (use { divider: true } for dividers) and various menu icon name updates.
+
+## 2025-12-31 - 3.17.0 - feat(editor)
+add file explorer toolbar, empty-space context menu, editor auto-save, save-all, and keyboard save shortcuts
+
+- Added filetree toolbar with New File / New Folder actions and toolbar styling

+- Implemented editor menu button with context menu (Auto Save toggle, Save, Save All)
+- Added auto-save toggle with 2s interval and cleanup on disconnect
+- Implemented Save and Save All APIs that persist files and update IntelliSense manager
+- Added keyboard shortcuts: Cmd/Ctrl+S to save active file and Cmd/Ctrl+Shift+S to save all
+- Made tabs scrollable with a tabs container and added an editor menu button
+
+## 2025-12-30 - 3.16.0 - feat(editor)
+improve TypeScript IntelliSense and module resolution for Monaco editor
+
+- Add file cache (fileCache) and getFileContent() for synchronous access to project files
+- Track and dispose Monaco extra libs (addedExtraLibs) and register project files via addExtraLib to enable TypeScript module resolution
+- Add addFileAsExtraLib logic to register .ts/.tsx files also under .js/.jsx paths so ESM imports resolve to TypeScript sources
+- Use ModuleResolutionKind.Bundler fallback to NodeJs and set compilerOptions (baseUrl '/', allowImportingTsExtensions, resolveJsonModule) to improve resolution
+- Adapt executionEnvironment API usage to readDir/readFile and check entry.type ('directory'|'file') instead of isDirectory/isFile
+- Add a debugging/screenshot asset: .playwright-mcp/module-resolution-fixed.png
+
+## 2025-12-30 - 3.15.0 - feat(editor)
+enable file-backed Monaco models and add Problems panel; lazy-init project TypeScript IntelliSense
+
+- dees-editor-monaco: add `filePath` property and create/get Monaco models with file:// URIs so editors are backed by real models; sync content into models and handle model switching when filePath changes; enable hover config and improved lifecycle handling.
+- dees-editor-workspace: add bottom 'Problems' panel and panel tabs (terminal/problems), diagnosticMarkers state, marker listener, UI for problem list, and navigation to file/position when a problem is clicked; initialize IntelliSense lazily when a file is opened.
+- typescript-intellisense: index project .ts/.js files from the virtual filesystem into Monaco models for cross-file resolution, enable allowNonTsExtensions and set eager model sync so TypeScript processes models eagerly.
+- General: improved handling for language changes, model language switching, and deferred initialization of the IntelliSense manager.
+- Add Playwright test images (workspace screenshots) used by CI/tests.
+
+## 2025-12-30 - 3.14.2 - fix(editor)
+bump monaco-editor to 0.55.1 and adapt TypeScript intellisense integration to the updated Monaco API
+
+- Bumped dependency monaco-editor from 0.52.2 to 0.55.1 in package.json.
+- Generated MONACO_VERSION module updated to 0.55.1 and moved target to ts_web/elements/00group-editor/dees-editor-monaco/version.ts.
+- Refactored TypeScript IntelliSense code to use a typed Monaco TS API (added IMonacoTypeScriptAPI, tsApi getter, and replaced direct monaco.languages.typescript.* calls).
+- Added test/workspace screenshot .playwright-mcp/workspace-test.png (binary asset).
+
+## 2025-12-30 - 3.14.1 - fix(build)
+bump @webcontainer/api and enable skipLibCheck to avoid type-check conflicts
+
+- Updated @webcontainer/api from 1.2.0 to 1.6.1
+- Added "skipLibCheck": true to tsconfig.json compilerOptions to suppress external library type errors
+- No breaking changes expected; this is a build/dev fix
+
+## 2025-12-30 - 3.14.0 - feat(editor)
+add modal prompts for file/folder creation, improve Monaco editor reactivity and add TypeScript IntelliSense support
+
+- Replace window.prompt for new file/folder with DeesModal + DeesInputText (showInputModal) to provide a focused modal input UX.
+- Monaco editor: add language property, handle external content updates without emitting change events (isUpdatingFromExternal), dispatch 'content-change' events, and apply language changes at runtime.
+- Add TypeScriptIntelliSenseManager to load .d.ts/type packages from the virtual filesystem (/node_modules), parse imports, load @types fallbacks, and add file models to Monaco for cross-file IntelliSense.
+- Workspace demo now mounts an initial TypeScript project and exposes initializationPromise to wait for external setup; workspace initializes IntelliSense and processes content changes to keep types up to date.
+- Export typescript-intellisense from workspace index so the manager is available to consumers.
+
+## 2025-12-30 - 3.13.1 - fix(webcontainer)
+prevent double initialization and race conditions when booting WebContainer and loading editor workspace/file tree
+
+- Add loadTreeStarted flag in dees-editor-filetree to avoid double-loading the file tree and reset it on refresh or on error to allow retries.
+- Add initializationStarted flag in dees-editor-workspace to prevent duplicate workspace initialization and reset it on initialization failure to allow retry.
+- Make WebContainerEnvironment use a shared singleton container and a bootPromise so only one WebContainer boot runs per page; instances wait for an ongoing boot instead of booting again.
+- Reset bootPromise/sharedContainer on boot failure and clear them on teardown so subsequent attempts can retry cleanly.
+
+## 2025-12-30 - 3.13.0 - feat(editor/runtime)
+Replace bare editor with Monaco-based editor and add runtime + workspace/filetree integration
+
+- Removed dees-editor-bare and replaced usages with dees-editor-monaco (includes MONACO_VERSION file).
+- Added IExecutionEnvironment interface and WebContainerEnvironment implementation (uses @webcontainer/api) to provide a browser Node/runtime API.
+- Added new components: dees-editor-filetree and dees-editor-workspace to support file tree, multiple open files, and workspace actions wired to the execution environment.
+- dees-terminal updated to accept an executionEnvironment (IExecutionEnvironment), renamed environment -> environmentVariables, provides environmentPromise (deprecated note), and now initializes/uses the provided environment to spawn shell processes and write /source.env.
+- Updated imports/usages across components (dees-input-code, dees-editor-markdown, group index exports) to use the new Monaco editor and runtime modules.
+- Behavioral breaking changes: consumers must supply an IExecutionEnvironment to components that now depend on it (e.g. dees-terminal, workspace, filetree); dees-editor-bare removal is a breaking API change.
+
+## 2025-12-30 - 3.12.2 - fix(dees-editor-bare)
+make Monaco editor follow domtools theme and clean up theme subscription on disconnect
+
+- Set initial Monaco theme from domtools.themeManager.goBrightBoolean instead of hardcoded 'vs-dark'
+- Subscribe to domtools.themeManager.themeObservable to update editor theme dynamically
+- Add monacoThemeSubscription property and unsubscribe in disconnectedCallback to avoid memory leaks
+
+## 2025-12-30 - 3.12.1 - fix(modal)
+fix modal editor layout to prevent overlap by adding relative positioning and reducing height
+
+- Added Playwright screenshots: .playwright-mcp/dees-input-code-demo.png and .playwright-mcp/modal-overlap-issue.png
+- Updated ts_web/elements/00group-input/dees-input-code/dees-input-code.ts: modal-editor-wrapper set position: relative and changed height from calc(100vh - 160px) to calc(100vh - 175px) to avoid overlap
+
+## 2025-12-30 - 3.12.0 - feat(editor)
+add code input component and editor-bare, replace dees-editor usage, and add modal contentPadding
+
+- Add new dees-input-code component (full-featured code editor input with modal, toolbar, language selector, copy and wrap toggles).
+- Introduce dees-editor-bare component and remove the legacy dees-editor implementation; update editor markdown component to use dees-editor-bare.
+- Export and include DeesInputCode in input index and include it in the unified form input types and dees-form usage.
+- Add contentPadding property to DeesModal and apply it to the modal content area (configurable modal inner padding).
+- Update element exports to point to dees-editor-bare and adjust related imports/usages.
+- Bump devDependency @design.estate/dees-wcctools from ^3.3.0 to ^3.4.0 in package.json
+
+## 2025-12-30 - 3.11.2 - fix(tests)
+make WYSIWYG tests more robust and deterministic by initializing and attaching elements consistently, awaiting customElements/firstUpdated, adjusting selectors and assertions, and cleaning up DOM after tests
+
+- Create WYSIWYG elements with document.createElement and set properties before attaching to DOM to ensure firstUpdated sees data
+- Await customElements.whenDefined and add small delays (setTimeout) so nested components finish rendering in test environments
+- Replace outdated selectors (.block.code) with .code-editor and update expectations for code block selection and language controls
+- Adjust divider expectations to check for <hr> and data-block-id instead of a divider icon; change toBeDefined -> toBeTruthy for assertions where appropriate
+- Add cleanup (document.body.removeChild) after tests to avoid leaking elements between tests
+- Relax computed font-family assertion to be platform-agnostic and verify that a fontFamily exists rather than matching 'monospace'
+- Add notes/guards around synthetic DragEvent/KeyboardEvent behavior: verify handlers/state existence and dispatch events but avoid relying on native focus/drag internals in CI
+- Update BlockRegistry render tests to assert template structure (data-block-id, data-block-type, class names) rather than final content which is populated later
+
+## 2025-12-30 - 3.11.1 - fix(tests)
+migrate tests to @git.zone/tstest tapbundle and export tap.start() in browser tests
+
+- Replaced imports from @push.rocks/tapbundle to @git.zone/tstest/tapbundle across test files
+- Replaced bare tap.start() calls with export default tap.start() in browser test files so the runner can be imported
+- Bumped devDependency @git.zone/tstest from ^3.1.3 to ^3.1.4 and removed @push.rocks/tapbundle from devDependencies
+- Changes include package.json and updates to multiple test files (11 test files)
+
+## 2025-12-30 - 3.11.0 - feat(dees-appui-tabs)
+improve horizontal tabs UX with scroll fades, hover scrollbar, and smooth scroll-to-selected
+
+- Add reactive scroll state (canScrollLeft / canScrollRight) and updateScrollState to track horizontal overflow.
+- Introduce scroll-fade gradient elements and CSS to indicate overflow on left/right edges.
+- Show a thin, styled scrollbar on hover (webkit + Firefox styling) instead of hiding it completely.
+- Auto-scroll selected tab into view using scrollTabIntoView and smooth scroll when selecting a tab.
+- Set up a ResizeObserver to recompute scroll state on container size changes and clean it up on disconnect.
+- Ensure lifecycle hooks call updateScrollState (firstUpdated/updated) so indicators stay in sync after render/fonts ready.
+
+## 2025-12-29 - 3.10.0 - feat(appui-tabs)
+add closeable tabs and auto-hide behavior for content tabs, plus API and events to control them
+
+- Add closeable tab support: IMenuItem.closeable & IMenuItem.onClose; dees-appui-tabs renders a close button, invokes onClose, and emits a 'tab-close' event.
+- Add auto-hide feature: dees-appui-tabs (autoHide, autoHideThreshold) and corresponding properties in dees-appui-maincontent/dees-appui-base to hide tabs when count ≤ threshold.
+- Expose new API: dees-appui-base.setContentTabsAutoHide(enabled, threshold) and update appconfig interface to include setContentTabsAutoHide.
+- Re-emit 'tab-close' events from dees-appui-maincontent and dees-appui-base so parent components can react to tab closures.
+- Add interactive demos (demo-closeable-tabs, demo-autohide-tabs) demonstrating the new closeable and auto-hide behaviors and controls.
+
+## 2025-12-29 - 3.9.0 - feat(dees-appui-mainmenu)
+add status badges to main menu items with theme-aware styling
+
+- Introduce .badge element and layout (min-width, height, padding, font-size, weight, border-radius) to display counts/status on menu items.
+- Add four badge variants: default, success, warning, error, using cssManager.bdTheme for light/dark color pairs.
+- Render the badge element conditionally in the menu item template when tabArg.badge is provided; hide badges when host has [collapsed] attribute.
+
+## 2025-12-29 - 3.8.0 - feat(dees-appui-base)
+add interactive demo controls to manipulate appui via view activation context
+
+- Store IViewActivationContext on the demo element (this.ctx) during onActivate
+- Add a new "Context Actions" UI section with buttons that call ctx.appui methods (toggle main/secondary menus, content tabs, collapse/expand main menu, set breadcrumbs, navigate to views, add activity entry, set/clear menu badges)
+- Include styles for ctx-actions and button variants (success, danger, hover states)
+- Change is limited to the demo file (dees-appui-base.demo.ts) and is non-breaking
+
+## 2025-12-29 - 3.7.1 - fix(dees-appui-maincontent)
+migrate main content layout to CSS Grid and enable topbar collapse transitions
+
+- Replace absolute positioning with CSS Grid on :host and .maincontainer to enable natural document flow
+- Make .topbar a grid and animate collapse via grid-template-rows; switch :host([notabs]) to grid-template-rows: 0fr instead of display:none to allow transitions
+- Set .maincontainer to display:contents and add min-height:0 on content areas and topbar children to fix overflow/scrolling and flex/grid height issues
+- Remove positional styles (position:absolute/top/left/right/bottom) so content scrolls correctly and layout is more robust
+
+## 2025-12-29 - 3.7.0 - feat(dees-contextmenu,dees-appui-tabs,test)
+Prevent double-destruction of context menus, await window layer teardown, update destroyAll behavior, remove tabs content slot, and adjust tests
+
+- Add isDestroying guard in DeesContextmenu.destroy to avoid double-destruction.
+- Await windowLayer.destroy() to ensure the window layer is fully torn down before continuing.
+- Ensure submenu timeouts are cleared and submenu.destroy() is awaited during teardown.
+- Change destroyAll to locate the root/top-level menu and destroy from the root to cascade teardown reliably.
+- Remove the .content wrapper and the <slot> output from dees-appui-tabs (demo updated to render content outside the component) — this is a breaking change to the tabs API (slotted content no longer rendered).
+- Increase test timeout in test.contextmenu-nested-close.browser.ts to 600ms to account for ~300ms windowLayer destruction + ~100ms context menu delay.
+
+## 2025-12-29 - 3.6.1 - fix(readme)
+document new App UI APIs to control main/secondary menu and content tabs visibility
+
+- Added docs for setMainMenuCollapsed(), setMainMenuVisible(), setSecondaryMenuCollapsed(), setSecondaryMenuVisible(), and setContentTabsVisible() programmatic APIs.
+- Included a TypeScript example showing how to hide secondary menu, hide content tabs, and collapse the main menu in a view's onActivate hook.
+
+## 2025-12-29 - 3.6.0 - feat(dees-appui)
+add visibility toggles for main/secondary menus and ability to show/hide content tabs; expose corresponding setters and appconfig entries
+
+- ts_web/elements/00group-appui/dees-appui-base: added boolean properties mainmenuVisible, secondarymenuVisible, maincontentTabsVisible; render main and secondary menus conditionally; pass showTabs to dees-appui-maincontent; added setter methods: setMainMenuVisible, setSecondaryMenuCollapsed, setSecondaryMenuVisible, setContentTabsVisible.
+- ts_web/elements/00group-appui/dees-appui-maincontent: added showTabs property, support for a notabs attribute via styles, updated() and firstUpdated() to apply notabs state so tabs can be hidden/shown dynamically.
+- ts_web/elements/interfaces/appconfig.ts: expanded appconfig interface to include setMainMenuVisible, setSecondaryMenuCollapsed, setSecondaryMenuVisible, setContentTabsVisible so host app can control visibility programmatically.
+- No breaking changes: defaults preserve existing behavior (menus and tabs remain visible by default).
+
+## 2025-12-29 - 3.5.1 - fix(dees-appui-view)
+remove DeesAppuiView component, its demo, documentation snippet, and related exports
+
+- Deleted component implementation: ts_web/elements/00group-appui/dees-appui-view/dees-appui-view.ts
+- Deleted demo file: ts_web/elements/00group-appui/dees-appui-view/dees-appui-view.demo.ts
+- Removed index re-export: ts_web/elements/00group-appui/dees-appui-view/index.ts (deleted) and removed export from ts_web/elements/00group-appui/index.ts
+- Removed documentation section for DeesAppuiView from readme.md
+- Breaking change: any consumers using the <dees-appui-view> component or its public API (selectTab, getMenuItems, getTabs) must be migrated to alternate components/approach
+
+## 2025-12-29 - 3.5.0 - feat(theme,interfaces)
+Introduce a global theming system and unify menu/tab interfaces; migrate components to use themeDefaultStyles and update APIs accordingly
+
+- Add a new theme module and component (00theme.ts + dees-theme) that provides CSS tokens and themeDefaultStyles to import into components
+- Migrate many components to include themeDefaultStyles in their static styles and add TODOs to replace hardcoded values with CSS variables
+- Rename ITab -> IMenuItem and replace group.tabs with group.items across interfaces and components (IMenuGroup shape changed) — this is a breaking API change
+- Remove legacy interfaces (ISecondaryMenuGroup, ISelectionOption) and update method and property types in DeesAppui* components and app config to use IMenuItem/IMenuGroup
+- Move @design.estate/dees-wcctools from dependencies to devDependencies and bump its version to ^3.3.0
+- Add numerous demo files and expand README with usage, examples and theme documentation
+
+## 2025-12-19 - 3.4.0 - feat(dees-appui-base)
+overhaul AppUI core: replace simple view rendering with a full-featured ViewRegistry (caching, hide/show lifecycle, async lazy-loading), introduce view lifecycle hooks and activation context, add activity log API/component, remove built-in router and state manager, and update configuration interfaces and demos
+
+- Removed files: app.router.ts and state.manager.ts — routing and state-persistence internals were removed (breaking).
+- ViewRegistry rewritten: supports cached instances, activate/deactivate lifecycle, canDeactivate checks, async content loading, parameterized routes, and legacy renderView kept as deprecated compatibility.
+- New interfaces added/changed: IViewActivationContext, IViewLifecycle, IActivityEntry, IActivityLogAPI, IViewLifecycleEvent; IViewDefinition.content now accepts async loaders and a cache flag; IMainMenuConfig and ITab expanded (logo, groups, badges).
+- Activity log: dees-appui-activitylog now implements IActivityLogAPI and exposes reactive entries; demo and readme updated with usage and examples.
+- App config changed: routing and statePersistence config entries removed/adjusted; defaultView moved into IAppConfig; view change and lifecycle event shapes changed (breaking).
+- Demos and documentation: dees-appui-base demo and readme added/updated to showcase new lifecycle hooks, secondary menu behavior, activity log and new APIs.
+
+## 2025-12-19 - 3.3.3 - fix(tests)
+update test imports to new dees-input-wysiwyg paths
+
+- Updated imports in test/test.wysiwyg-registry.both.ts to point to ts_web/elements/00group-input/dees-input-wysiwyg/*
+- Aligns test references with relocated WYSIWYG block handlers and block registration module; no behavior changes to implementation
+
+## 2025-12-19 - 3.3.2 - fix(build)
+update build config, bump dependencies, and adjust test import paths after element reorganization
+
+- npmextra.json: renamed gitzone entry to @git.zone/cli, moved tsdoc key to @git.zone/tsdoc, added @ship.zone/szci entry and added release registries + accessLevel
+- package.json: bumped @design.estate/dees-wcctools ^2.0.1 -> ^3.1.0, lucide ^0.560.0 -> ^0.562.0, @git.zone/tsbuild ^3.1.2 -> ^4.0.2, @types/node ^25.0.0 -> ^25.0.3
+- tests: updated import paths to follow reorganized source layout (wysiwyg files moved under elements/00group-input/dees-input-wysiwyg and dees-contextmenu moved to elements/dees-contextmenu/dees-contextmenu.js); updated BlockRegistry and blockregistration import paths
+- Purpose: align tests and build metadata with refactored element file locations and updated tool/dependency versions
+
+## 2025-12-11 - 3.3.1 - fix(dees-pdf-viewer)
+Scroll active PDF thumbnail into view after rendering and on page changes; update dependency versions
+
+- Ensure the active thumbnail is scrolled into view after thumbnails are rendered (improves sidebar navigation for dees-pdf-viewer).
+- Scroll the thumbnail into view when navigating pages if the sidebar is visible (prevents the active page from being off-screen).
+- Retain re-setup of the intersection observer for lazy-loading pages after thumbnail re-render.
+- Bumped dependencies in package.json: @design.estate/dees-wcctools -> ^2.0.1, lucide -> ^0.560.0, @git.zone/tswatch -> ^2.3.13, @types/node -> ^25.0.0.
+
+## 2025-12-09 - 3.3.0 - feat(dees-appui-base)
+Add unified App UI API to dees-appui-base with ViewRegistry, AppRouter and StateManager
+
+- Introduce ViewRegistry for declarative view registration and rendering (supports tag names, element classes and template functions).
+- Add AppRouter with hash/history/external/none modes, URL synchronization, navigate/back/forward and onRouteChange listener support.
+- Add StateManager to persist UI state (localStorage, sessionStorage or in-memory) with save/load/update/clear APIs.
+- Extend interfaces (interfaces/appconfig.ts) with IAppConfig, IViewDefinition, IRoutingConfig, IStatePersistenceConfig and IAppUIState.
+- Expose new public DeesAppuiBase methods: configure, navigateToView, getCurrentView, getUIState, restoreUIState, saveState, loadState, getViewRegistry, getRouter.
+- Maintain backward compatibility with existing property-based API and slot usage.
+- Export new modules (view.registry, app.router, state.manager) from dees-appui-base index and update element exports.
+
 ## 2025-12-08 - 3.2.0 - feat(dees-simple-appdash,dees-simple-login,dees-terminal)
 Revamp UI: dashboard & login styling, standardize icons to Lucide, and add terminal background/config

+## Enhanced AppUI API (2025-12-08)
+
+The `dees-appui-base` component has been enhanced with a unified configuration API for building real-world applications.
+
+### New Modules:
+
+1. **ViewRegistry** (`view.registry.ts`)
+   - Manages view definitions and their lifecycle
+   - Supports tag names, element classes, and template functions as view content
+   - Methods: register, get, renderView, findByRoute
+
+2. **AppRouter** (`app.router.ts`)
+   - Built-in routing with hash or history mode
+   - External router support for framework integration
+   - Methods: navigate, back, forward, onRouteChange
+
+3. **StateManager** (`state.manager.ts`)
+   - Persists UI state (collapsed menus, selections, current view)
+   - Supports localStorage, sessionStorage, or memory storage
+   - Methods: save, load, update, clear
+
+### New Interfaces (in `interfaces/appconfig.ts`):
+
+```typescript
+interface IAppConfig {
+  branding?: { logoIcon?: string; logoText?: string };
+  appBar?: IAppBarConfig;
+  views: IViewDefinition[];
+  mainMenu?: IMainMenuConfig;
+  routing?: IRoutingConfig;
+  statePersistence?: IStatePersistenceConfig;
+  onViewChange?: (viewId: string, view: IViewDefinition) => void;
+}
+
+interface IViewDefinition {
+  id: string;
+  name: string;
+  iconName?: string;
+  content: string | (new () => HTMLElement) | (() => TemplateResult);
+  secondaryMenu?: ISecondaryMenuGroup[];
+  contentTabs?: ITab[];
+  route?: string;
+}
+
+interface IRoutingConfig {
+  mode: 'hash' | 'history' | 'external' | 'none';
+  basePath?: string;
+  defaultView?: string;
+  syncUrl?: boolean;
+}
+```
+
+### New Public Methods on DeesAppuiBase:
+
+```typescript
+// Configure with unified config
+configure(config: IAppConfig): void
+
+// Navigation
+navigateToView(viewId: string): boolean
+getCurrentView(): IViewDefinition | undefined
+
+// State management
+getUIState(): IAppUIState
+restoreUIState(state: IAppUIState): void
+saveState(): void
+loadState(): boolean
+
+// Access internals
+getViewRegistry(): ViewRegistry
+getRouter(): AppRouter | null
+```
+
+### Usage Example (New Unified Config API):
+
+```typescript
+import type { IAppConfig } from '@design.estate/dees-catalog';
+
+const config: IAppConfig = {
+  branding: { logoIcon: 'lucide:box', logoText: 'My App' },
+  views: [
+    { id: 'dashboard', name: 'Dashboard', iconName: 'lucide:home', content: 'my-dashboard' },
+    { id: 'settings', name: 'Settings', iconName: 'lucide:settings', content: 'my-settings' },
+  ],
+  mainMenu: {
+    sections: [{ views: ['dashboard'] }],
+    bottomItems: ['settings'],
+  },
+  routing: { mode: 'hash', defaultView: 'dashboard' },
+  statePersistence: { enabled: true, storage: 'localStorage' },
+};
+
+html`<dees-appui-base .config=${config}></dees-appui-base>`;
+```
+
+### Backward Compatibility:
+
+The existing property-based API still works:
+
+```typescript
+html`
+  <dees-appui-base
+    .mainmenuGroups=${groups}
+    .secondarymenuGroups=${secondaryGroups}
+    @mainmenu-tab-select=${handler}
+  >
+    <div slot="maincontent">...</div>
+  </dees-appui-base>
+`;
+```
+
+### Key Features:
+
+- **Declarative View Registry**: Map menu items to view components
+- **Built-in Routing**: Hash or history mode with URL synchronization
+- **External Router Support**: Integrate with Angular Router or other frameworks
+- **State Persistence**: Save/restore collapsed menus, selections, and current view
+- **View-specific Menus**: Each view can define its own secondary menu and tabs
+- **Full Backward Compatibility**: Existing code continues to work

+# DeesAppuiBase
+
+A comprehensive application shell component providing a complete UI framework with navigation, menus, activity logging, and view management.
+
+## Quick Start
+
+```typescript
+import { html, DeesElement, customElement } from '@design.estate/dees-element';
+import { DeesAppuiBase } from '@design.estate/dees-catalog';
+
+@customElement('my-app')
+class MyApp extends DeesElement {
+  private appui: DeesAppuiBase;
+
+  async firstUpdated() {
+    this.appui = this.shadowRoot.querySelector('dees-appui-base');
+
+    // Configure with views and menu
+    this.appui.configure({
+      branding: { logoIcon: 'lucide:box', logoText: 'My App' },
+      views: [
+        { id: 'dashboard', name: 'Dashboard', iconName: 'lucide:home', content: 'my-dashboard' },
+        { id: 'settings', name: 'Settings', iconName: 'lucide:settings', content: 'my-settings' },
+      ],
+      mainMenu: {
+        sections: [{ name: 'Main', views: ['dashboard', 'settings'] }]
+      },
+      defaultView: 'dashboard'
+    });
+  }
+
+  render() {
+    return html`<dees-appui-base></dees-appui-base>`;
+  }
+}
+```
+
+## Configuration API
+
+### `configure(config: IAppConfig)`
+
+Configure the entire application shell with a single configuration object.
+
+```typescript
+interface IAppConfig {
+  branding?: IBrandingConfig;
+  appBar?: IAppBarConfig;
+  views: IViewDefinition[];
+  mainMenu?: IMainMenuConfig;
+  defaultView?: string;
+  activityLog?: IActivityLogConfig;
+  onViewChange?: (viewId: string, view: IViewDefinition) => void;
+  onSearch?: (query: string) => void;
+}
+```
+
+### View Definition
+
+```typescript
+interface IViewDefinition {
+  id: string;                           // Unique identifier
+  name: string;                         // Display name
+  iconName?: string;                    // Icon (e.g., 'lucide:home')
+  content:                              // View content
+    | string                            // Tag name ('my-component')
+    | (new () => HTMLElement)           // Class constructor
+    | (() => TemplateResult)            // Template function
+    | (() => Promise<...>);             // Async for lazy loading
+  secondaryMenu?: ISecondaryMenuGroup[];
+  contentTabs?: ITab[];
+  route?: string;                       // URL route (default: id)
+  badge?: string | number;
+  cache?: boolean;                      // Cache view instance (default: true)
+}
+```
+
+---
+
+## Programmatic APIs
+
+### App Bar API
+
+Control the top application bar.
+
+```typescript
+// Set menu items (File, Edit, View, etc.)
+appui.setAppBarMenus([
+  {
+    name: 'File',
+    submenu: [
+      { name: 'New', shortcut: 'Cmd+N', action: () => {} },
+      { name: 'Save', shortcut: 'Cmd+S', action: () => {} },
+    ]
+  }
+]);
+
+// Update single menu
+appui.updateAppBarMenu('File', { submenu: [...newItems] });
+
+// Breadcrumbs
+appui.setBreadcrumbs('Dashboard > Settings > Profile');
+appui.setBreadcrumbs(['Dashboard', 'Settings', 'Profile']);
+
+// User profile
+appui.setUser({
+  name: 'John Doe',
+  email: 'john@example.com',
+  avatar: '/avatars/john.png',
+  status: 'online'  // 'online' | 'offline' | 'busy' | 'away'
+});
+
+appui.setProfileMenuItems([
+  { name: 'Profile', iconName: 'lucide:user', action: () => {} },
+  { divider: true },
+  { name: 'Sign Out', iconName: 'lucide:log-out', action: () => {} }
+]);
+
+// Search
+appui.setSearchVisible(true);
+appui.onSearch((query) => console.log('Search:', query));
+
+// Window controls (for Electron/Tauri apps)
+appui.setWindowControlsVisible(false);
+```
+
+### Main Menu API (Left Sidebar)
+
+Control the main navigation menu.
+
+```typescript
+// Set entire menu
+appui.setMainMenu({
+  logoIcon: 'lucide:box',
+  logoText: 'My App',
+  groups: [
+    {
+      name: 'Main',
+      tabs: [
+        { key: 'dashboard', iconName: 'lucide:home', action: () => {} },
+        { key: 'inbox', iconName: 'lucide:inbox', badge: 5, action: () => {} },
+      ]
+    }
+  ],
+  bottomTabs: [
+    { key: 'settings', iconName: 'lucide:settings', action: () => {} }
+  ]
+});
+
+// Update specific group
+appui.updateMainMenuGroup('Main', { tabs: [...newTabs] });
+
+// Add/remove items
+appui.addMainMenuItem('Main', { key: 'tasks', iconName: 'lucide:check', action: () => {} });
+appui.removeMainMenuItem('Main', 'tasks');
+
+// Selection
+appui.setMainMenuSelection('dashboard');
+appui.setMainMenuCollapsed(true);
+
+// Badges
+appui.setMainMenuBadge('inbox', 12);
+appui.clearMainMenuBadge('inbox');
+```
+
+### Secondary Menu API
+
+Views can control the secondary (contextual) menu.
+
+```typescript
+// Set menu
+appui.setSecondaryMenu({
+  heading: 'Settings',
+  groups: [
+    {
+      name: 'Account',
+      items: [
+        { key: 'profile', iconName: 'lucide:user', action: () => {} },
+        { key: 'security', iconName: 'lucide:shield', action: () => {} },
+      ]
+    }
+  ]
+});
+
+// Update group
+appui.updateSecondaryMenuGroup('Account', { items: newItems });
+
+// Add item
+appui.addSecondaryMenuItem('Account', {
+  key: 'notifications',
+  iconName: 'lucide:bell',
+  action: () => {}
+});
+
+// Selection
+appui.setSecondaryMenuSelection('profile');
+
+// Clear
+appui.clearSecondaryMenu();
+```
+
+### Content Tabs API
+
+Control tabs in the main content area.
+
+```typescript
+// Set tabs
+appui.setContentTabs([
+  { key: 'code', iconName: 'lucide:code', action: () => {} },
+  { key: 'preview', iconName: 'lucide:eye', action: () => {} }
+]);
+
+// Add/remove
+appui.addContentTab({ key: 'debug', iconName: 'lucide:bug', action: () => {} });
+appui.removeContentTab('debug');
+
+// Select
+appui.selectContentTab('preview');
+
+// Get current
+const current = appui.getSelectedContentTab();
+```
+
+### Activity Log API
+
+Add activity entries to the right-side activity log.
+
+```typescript
+// Add single entry
+appui.activityLog.add({
+  type: 'create',       // 'login' | 'logout' | 'view' | 'create' | 'update' | 'delete' | 'custom'
+  user: 'John Doe',
+  message: 'created a new invoice',
+  iconName: 'lucide:file-plus',  // Optional custom icon
+  data: { invoiceId: '123' }     // Optional metadata
+});
+
+// Add multiple
+appui.activityLog.addMany([...entries]);
+
+// Clear
+appui.activityLog.clear();
+
+// Query
+const entries = appui.activityLog.getEntries();
+const filtered = appui.activityLog.filter({ user: 'John', type: 'create' });
+const searched = appui.activityLog.search('invoice');
+```
+
+### Navigation API
+
+Navigate between views programmatically.
+
+```typescript
+// Navigate to view
+await appui.navigateToView('settings');
+await appui.navigateToView('settings', { section: 'profile' });
+
+// Get current view
+const current = appui.getCurrentView();
+
+// Subscribe to view changes
+appui.viewChanged$.subscribe((event) => {
+  console.log(`Navigated to: ${event.viewId}`);
+});
+
+// Subscribe to lifecycle events
+appui.viewLifecycle$.subscribe((event) => {
+  if (event.type === 'activated') {
+    console.log(`View ${event.viewId} activated`);
+  }
+});
+```
+
+---
+
+## View Lifecycle Hooks
+
+Views can implement lifecycle hooks to respond to activation/deactivation.
+
+```typescript
+import { DeesElement, customElement } from '@design.estate/dees-element';
+import type { IViewActivationContext, IViewLifecycle } from '@design.estate/dees-catalog';
+
+@customElement('my-settings-view')
+class MySettingsView extends DeesElement implements IViewLifecycle {
+  /**
+   * Called when view is activated (displayed)
+   * Receives typed context with appui reference
+   */
+  async onActivate(context: IViewActivationContext) {
+    const { appui, viewId, params } = context;
+
+    // Set view-specific secondary menu
+    appui.setSecondaryMenu({
+      heading: 'Settings',
+      groups: [{ name: 'Options', items: [...] }]
+    });
+
+    // Set view-specific tabs
+    appui.setContentTabs([...]);
+
+    // Load data based on route params
+    if (params?.section) {
+      await this.loadSection(params.section);
+    }
+  }
+
+  /**
+   * Called when view is deactivated (hidden)
+   */
+  onDeactivate() {
+    this.cleanup();
+  }
+
+  /**
+   * Called before navigation away
+   * Return false or a message string to block navigation
+   */
+  canDeactivate(): boolean | string {
+    if (this.hasUnsavedChanges) {
+      return 'You have unsaved changes. Leave anyway?';
+    }
+    return true;
+  }
+}
+```
+
+### IViewActivationContext
+
+```typescript
+interface IViewActivationContext {
+  appui: DeesAppuiBase;           // Reference to the app shell
+  viewId: string;                  // The view ID being activated
+  params?: Record<string, string>; // Route parameters
+}
+```
+
+---
+
+## Routing
+
+Routes are automatically registered from view definitions using `domtools.router`.
+
+```typescript
+const views = [
+  { id: 'dashboard', route: 'dashboard', ... },
+  { id: 'settings', route: 'settings/:section?', ... },  // Parameterized
+  { id: 'user', route: 'users/:id', ... },
+];
+
+// URL: #dashboard → navigates to dashboard view
+// URL: #settings/profile → navigates to settings with params.section = 'profile'
+// URL: #users/123 → navigates to user with params.id = '123'
+```
+
+### Hash-based Routing
+
+The router uses hash-based routing by default (`#viewId`). URLs are automatically synchronized when navigating via `navigateToView()`.
+
+---
+
+## View Caching
+
+Views are cached by default. When navigating away and back, the same DOM element is reused (hidden/shown) rather than destroyed and recreated.
+
+```typescript
+// Disable caching for a specific view
+{
+  id: 'reports',
+  name: 'Reports',
+  content: 'my-reports-view',
+  cache: false  // Always recreate this view
+}
+```
+
+---
+
+## Lazy Loading
+
+Use async content functions for lazy loading views.
+
+```typescript
+{
+  id: 'analytics',
+  name: 'Analytics',
+  content: async () => {
+    const module = await import('./views/analytics.js');
+    return module.AnalyticsView;
+  }
+}
+```
+
+---
+
+## RxJS Observables
+
+The component exposes RxJS Subjects for reactive programming.
+
+```typescript
+// View lifecycle events
+appui.viewLifecycle$.subscribe((event) => {
+  // event.type: 'loading' | 'activated' | 'deactivated' | 'loaded' | 'loadError'
+  // event.viewId: string
+  // event.element?: HTMLElement
+  // event.params?: Record<string, string>
+  // event.error?: unknown
+});
+
+// View change events
+appui.viewChanged$.subscribe((event) => {
+  // event.viewId: string
+  // event.view: IViewDefinition
+  // event.previousView?: IViewDefinition
+  // event.params?: Record<string, string>
+});
+```
