 # Changelog
 
+## 2026-01-03 - 3.29.0 - feat(docs)
+add documentation for new input components, activity log features, theming, and expand DeesAppui docs
+
+- Updated top-level README to reflect component count increase (75+ → 80+) and added many new component docs
+- Added documentation and examples for DeesInputList (sortable list input) and DeesInputProfilepicture (cropping, upload, processing)
+- Introduced DeesTheme documentation with usage examples and CSS custom property overrides
+- Expanded DeesAppui readme with architecture overview, activity log panel docs, activity entry types, and navigation/secondary menu guidance
+- Documented activity log APIs and controls (activityLog.add, addMany, clear, getEntries, filter, search) and new control API helpers (setActivityLogVisible, toggleActivityLog, getActivityLogVisible)
+- Updated Appbar examples to include activity log toggle properties (.showActivityLogToggle, .activityLogCount, .activityLogActive) and @activity-toggle event
+- Added interface docs (IViewDefinition, IActivityEntry) and updated menu/secondary menu type references
+- Changes are documentation-focused (README/element readmes); no source code logic changes shown in this diff
+
+## 2026-01-03 - 3.28.1 - fix(appui)
+adjust layout and spacing in app UI components: fix activity log overflow, contain main content overscroll, and refine secondary menu padding/transition
+
+- ts_web/elements/00group-appui/dees-appui-activitylog: removed host max-width, added overflow:hidden and set .maincontainer width to 280px to prevent horizontal overflow
+- ts_web/elements/00group-appui/dees-appui-maincontent: added overscroll-behavior: contain to .content-area to prevent scroll chaining/overscroll
+- ts_web/elements/00group-appui/dees-appui-secondarymenu: updated .groupHeader padding and hover border behavior, increased group icon size from 14px to 16px, and added margin + transition tweaks to .groupItems for smoother collapse/expand
+
+## 2026-01-02 - 3.28.0 - feat(dees-appui)
+Rename DeesAppuiBase to DeesAppui and migrate related API, exports, demos and docs
+
+- Renamed public component/tag and TypeScript types: DeesAppuiBase -> DeesAppui and TDeesAppuiBase -> TDeesAppui; updated IViewActivationContext.appui type accordingly
+- Moved/rewired view registry implementation from dees-appui-base to dees-appui and updated module exports
+- Updated README and demo files to reference DeesAppui and new readme paths (removed dees-appui-base docs/demo)
+- Replaced dependency/imports of '@webcontainer/api' with '@tempfix/webcontainer__api' (package.json and source imports)
+- Changed tsconfig.json: skipLibCheck set from true to false
+
+## 2026-01-01 - 3.27.1 - fix(dees-actionbar)
+always render actionbar wrapper and delay adding visible class to ensure grid/opacity animations run reliably
+
+- Always render the actionbar wrapper (.actionbar-item and .actionbar-content) instead of returning early so grid-template-rows and opacity transitions can animate.
+- Use optional chaining for current bar access (bar?.type, bar?.timeout) to avoid runtime errors when no bar is present.
+- Adjust styles and structure: set :host display:block; move background/border to .actionbar-item; add .actionbar-content with min-height/opacity and transitions.
+- Make processQueue asynchronous and await updateComplete, then add the 'visible' class inside requestAnimationFrame so the CSS transition is triggered after render.
+
+## 2026-01-01 - 3.27.0 - feat(services)
+introduce DeesServiceLibLoader to lazy-load heavy client libraries from CDN and update components to use it
+
+- Add DeesServiceLibLoader singleton (ts_web/services/DeesServiceLibLoader.ts) to lazily load and cache libraries via jsDelivr ESM: xterm, xterm-addon-fit, highlight.js, ApexCharts, and Tiptap.
+- Inject xterm CSS dynamically to avoid shipping xterm styles in the initial bundle.
+- Expose helper methods preloadAll() and isLoaded(), and typed bundle interfaces (IXtermBundle, IXtermFitAddonBundle, ITiptapBundle).
+- Update components to use runtime-loaded modules: dees-chart-area, dees-dataview-codebox, dees-input-richtext, wysiwyg code block, dees-workspace-terminal, terminal-tab-manager, dees-workspace-terminal-preview.
+- TerminalTabManager now requires setXtermModules(...) before creating tabs and will throw if not initialized; workspace terminal now initializes and passes the loaded modules.
+- Replace direct runtime imports of heavy libs with typed imports and runtime-loaded bundles to reduce initial bundle size and improve load performance.
+
+## 2026-01-01 - 3.26.1 - fix(dees-actionbar)
+animate actionbar hide using grid-template-rows and wait for animation before clearing state
+
+- Switch host layout from block/max-height to grid using grid-template-rows for open/close transitions
+- Add min-height: 0 to .actionbar-item to prevent flex children overflow and collapsing
+- Introduce async hideCurrentBar() that removes 'visible', sets isVisible=false, waits 220ms then clears currentBar and currentResolve
+- processQueue() now calls hideCurrentBar() asynchronously instead of clearing state immediately
+
+## 2026-01-01 - 3.26.0 - feat(workspace)
+add external file change detection, conflict resolution UI, and diff editor
+
+- Watch open files for external changes with debounced file watchers (startWatchingFile/stopWatchingFile/stopAllFileWatchers).
+- Prompt the user when disk changes conflict with unsaved local edits via dees-actionbar (actions: Load from Disk, Save Local, Compare).
+- Introduce dees-workspace-diff-editor component and export it; support comparing and resolving diffs (diff-resolved / diff-closed events).
+- Add setContentExternal in dees-workspace-monaco to update editor content from external sources while optionally preserving cursor, selections and scroll position.
+- Start/stop file watchers when files are opened/closed and integrate diff view and actionbar into the workspace UI for seamless conflict handling.
+
+## 2026-01-01 - 3.25.0 - feat(dees-actionbar)
+add action bar component and improve workspace package update handling
+
+- Introduce dees-actionbar component (dees-actionbar.ts) with interfaces, queueing, timed auto-trigger and demo usage
+- Add actionbar.interfaces.ts and index export; export dees-actionbar from elements index
+- Enhance workspace bottombar: add pendingPackageUpdate flag, process-complete handler, and connected/disconnected listeners to auto-refresh package status after updates
+- Make pnpm outdated checking robust by streaming output via a reader and adding a 10s timeout to avoid hanging; handle timeout and stream cancellation
+- Update package update commands to include '--latest' for updatePackage and updateAllPackages, and show 'Checking...' label during checks
+- Add '@types/node' (^22.0.0) to devDependencies in the workspace package config
+
+## 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
+- Add mouse event handlers (mousedown/move/up) to drag-resize the file tree and terminal with min/max clamping
+- Dispatch window resize event after resizing to notify Monaco/editor of layout changes
+- Clean up resize event listeners in disconnectedCallback
+- Initialize current sizes from component properties in firstUpdated
+- 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
+- Added right-click context menu for empty filetree space to create files/folders
+- 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

+
+- **Settings pages** (grouped settings categories)
+- **File browsers** (folder trees)
+- **Project navigation** (grouped by category)
+- **Documentation** (chapters/sections)
+
+### Collapsible Groups
+
+Groups can be collapsed/expanded by clicking the group header. The state is visually indicated with an icon rotation.
 
 ```typescript
-// Set menu
+// Set secondary menu with collapsible groups
 appui.setSecondaryMenu({
   heading: 'Settings',
   groups: [
     {
       name: 'Account',
+      iconName: 'lucide:user',        // Group icon
+      collapsed: false,                // Initial state (default: false)
       items: [
-        { key: 'profile', iconName: 'lucide:user', action: () => {} },
+        { key: 'profile', iconName: 'lucide:user', action: () => showProfile() },
-        { key: 'security', iconName: 'lucide:shield', action: () => {} },
+        { key: 'security', iconName: 'lucide:shield', badge: '!', badgeVariant: 'warning', action: () => showSecurity() },
+        { key: 'billing', iconName: 'lucide:credit-card', action: () => showBilling() }
+      ]
+    },
+    {
+      name: 'Preferences',
+      iconName: 'lucide:settings',
+      collapsed: true,                 // Start collapsed
+      items: [
+        { key: 'notifications', iconName: 'lucide:bell', action: () => {} },
+        { key: 'appearance', iconName: 'lucide:palette', action: () => {} },
+        { key: 'language', iconName: 'lucide:globe', action: () => {} }
       ]
     }
   ]
 });
+```
 
-// Update group
+### Secondary Menu Item Properties
-appui.updateSecondaryMenuGroup('Account', { items: newItems });
 
-// Add item
+```typescript
-appui.addSecondaryMenuItem('Account', {
+interface ISecondaryMenuItem {
-  key: 'notifications',
+  key: string;                    // Unique identifier
-  iconName: 'lucide:bell',
+  iconName?: string;              // Icon (e.g., 'lucide:user')
-  action: () => {}
+  action: () => void;             // Click handler
+  badge?: string | number;        // Badge text/count
+  badgeVariant?: 'default' | 'success' | 'warning' | 'error';
+}
+
+interface ISecondaryMenuGroup {
+  name: string;                   // Group name (shown in header)
+  iconName?: string;              // Group icon
+  collapsed?: boolean;            // Initial collapsed state
+  items: ISecondaryMenuItem[];    // Items in this group
+}
+```
+
+### Updating Secondary Menu
+
+```typescript
+// Update a specific group
+appui.updateSecondaryMenuGroup('Account', {
+  items: [...newItems]
 });
 
-// Selection
+// Add item to a group
+appui.addSecondaryMenuItem('Account', {
+  key: 'api-keys',
+  iconName: 'lucide:key',
+  action: () => showApiKeys()
+});
+
+// Selection (highlights the item)
 appui.setSecondaryMenuSelection('profile');
 
+// Visibility control
+appui.setSecondaryMenuCollapsed(true);   // Collapse panel
+appui.setSecondaryMenuVisible(false);     // Hide completely
+
 // Clear
 appui.clearSecondaryMenu();
 ```
 
-### Content Tabs API
+### View-Specific Secondary Menus
 
-Control tabs in the main content area.
+Each view can define its own secondary menu that appears when the view is activated:
 
 ```typescript
-// Set tabs
+// In view definition
-appui.setContentTabs([
+{
-  { key: 'code', iconName: 'lucide:code', action: () => {} },
+  id: 'settings',
-  { key: 'preview', iconName: 'lucide:eye', action: () => {} }
+  name: 'Settings',
-]);
+  content: 'my-settings-view',
+  secondaryMenu: [
+    {
+      name: 'General',
+      items: [
+        { key: 'account', iconName: 'lucide:user', action: () => {} },
+        { key: 'security', iconName: 'lucide:shield', action: () => {} }
+      ]
+    }
+  ]
+}
 
-// Add/remove
+// Or set dynamically in view's onActivate hook
-appui.addContentTab({ key: 'debug', iconName: 'lucide:bug', action: () => {} });
+onActivate(context: IViewActivationContext) {
-appui.removeContentTab('debug');
+  context.appui.setSecondaryMenu({
-
+    heading: 'Project Files',
-// Select
+    groups: [...]
-appui.selectContentTab('preview');
+  });
-
+}
-// Get current
-const current = appui.getSelectedContentTab();
 ```
 
-### Activity Log API
+---
 
-Add activity entries to the right-side activity log.
+## Content Tabs API 📑
+
+Content tabs appear above the main view content. They're designed for **opening multiple items** from tables, lists, or other data sources—similar to browser tabs or IDE editor tabs.
+
+### Common Use Cases
+
+- **Table row details** - Click a row to open it as a tab
+- **Document editing** - Open multiple documents
+- **Entity inspection** - View customer, order, product details
+- **Multi-file editing** - Edit multiple configuration files
+
+### Closable Tabs
+
+Tabs can be closable, allowing users to open items, work with them, and close when done:
+
+```typescript
+// Set initial tabs
+appui.setContentTabs([
+  { key: 'overview', iconName: 'lucide:home', action: () => showOverview() },
+  { key: 'activity', iconName: 'lucide:activity', action: () => showActivity() }
+]);
+
+// Add a closable tab when user clicks a table row
+table.addEventListener('row-click', (e) => {
+  const item = e.detail.item;
+
+  appui.addContentTab({
+    key: `item-${item.id}`,
+    label: item.name,                      // Display label
+    iconName: 'lucide:file',
+    closable: true,                        // Allow closing
+    action: () => showItemDetails(item)
+  });
+
+  // Select the new tab
+  appui.selectContentTab(`item-${item.id}`);
+});
+
+// Handle tab close
+appui.addEventListener('tab-close', (e) => {
+  const tabKey = e.detail.key;
+  // Cleanup resources if needed
+  console.log(`Tab ${tabKey} closed`);
+});
+```
+
+### Tab Management
+
+```typescript
+// Add/remove tabs
+appui.addContentTab({
+  key: 'debug',
+  iconName: 'lucide:bug',
+  closable: true,
+  action: () => {}
+});
+appui.removeContentTab('debug');
+
+// Select tab
+appui.selectContentTab('preview');
+
+// Get current tab
+const current = appui.getSelectedContentTab();
+
+// Visibility control
+appui.setContentTabsVisible(false);        // Hide tab bar
+
+// Auto-hide when only one tab
+appui.setContentTabsAutoHide(true, 1);     // Hide when ≤ 1 tab
+```
+
+### Opening Items from Tables/Lists
+
+A common pattern is opening table rows as closable tabs:
+
+```typescript
+@customElement('my-customers-view')
+class MyCustomersView extends DeesElement {
+  private appui: DeesAppui;
+
+  onActivate(context: IViewActivationContext) {
+    this.appui = context.appui;
+
+    // Set base tabs
+    this.appui.setContentTabs([
+      { key: 'list', label: 'All Customers', iconName: 'lucide:users', action: () => this.showList() }
+    ]);
+  }
+
+  render() {
+    return html`
+      <dees-table
+        .data=${this.customers}
+        @row-dblclick=${this.openCustomerTab}
+      ></dees-table>
+    `;
+  }
+
+  openCustomerTab(e: CustomEvent) {
+    const customer = e.detail.item;
+    const tabKey = `customer-${customer.id}`;
+
+    // Check if tab already exists
+    const existingTab = this.appui.getSelectedContentTab();
+    if (existingTab?.key === tabKey) {
+      return; // Already viewing this customer
+    }
+
+    // Add new closable tab
+    this.appui.addContentTab({
+      key: tabKey,
+      label: customer.name,
+      iconName: 'lucide:user',
+      closable: true,
+      action: () => this.showCustomerDetails(customer)
+    });
+
+    this.appui.selectContentTab(tabKey);
+  }
+
+  showCustomerDetails(customer: Customer) {
+    // Render customer details
+    this.currentView = html`<customer-details .customer=${customer}></customer-details>`;
+  }
+
+  showList() {
+    this.currentView = html`<dees-table ...></dees-table>`;
+  }
+}
+```
+
+---
+
+## Activity Log API 📊
+
+The activity log is a slide-out panel on the right side showing user actions and system events.
+
+### Activity Log Toggle
+
+The appbar includes a toggle button with a badge showing the entry count:
+
+```typescript
+// Control visibility
+appui.setActivityLogVisible(true);     // Show panel
+appui.toggleActivityLog();             // Toggle state
+const isVisible = appui.getActivityLogVisible();
+
+// The toggle button automatically shows entry count
+// Add entries and the badge updates automatically
+```
+
+### Adding Entries
 
 ```typescript
 // Add single entry
