1.2.0

- Introduced async demo functionality in the README, allowing for asynchronous data preparation before rendering components.
- Updated WccDashboard, WccProperties, and WccSidebar to support Promise-based template factories.
- Implemented resolveTemplateFactory to handle both synchronous and asynchronous template results.
- Added tests for resolveTemplateFactory to ensure correct behavior for both sync and async templates.
- Updated pnpm workspace configuration.

 # Changelog
 
+## 2025-09-19 - 1.2.0 - feat(wcc-properties)
+Add advanced property editors, recursive element detection, demo wrapper, UI refresh and test fixtures
+
+- Advanced JSON property editor: multiple side-by-side editors with save/cancel, syntax validation and inline error display; editors affect frame layout (frame bottom increases when editors open).
+- Improved properties panel element detection: recursive search through nested children and shadow DOM, initial delay and retry mechanism to handle async Lit rendering.
+- Add dees-demowrapper component in ts_demotools to run post-render callbacks and support async demo setup and DOM access for demos.
+- UI refresh with shadcn-like styles: CSS variables for theming, redesigned properties panel and sidebar, improved form controls, theme and viewport selectors.
+- Viewport and frame improvements: responsive padding based on viewport type, theme-aware background rendering, and scroll position tracking with URL/state restoration for frame and sidebar.
+- Add test fixtures and demo elements/pages under test/ to exercise properties, complex types, nested elements and scroll restoration; include node test for resolveTemplateFactory.
+- Expose setupWccTools entry point and plugin wiring (wcctools.plugins exports for dees-domtools and smartdelay) for easier integration.
+
 ## 2025-06-27 - 1.1.0 - feat(wcctools)
 Enhance component tools with an advanced property editor, improved element detection and modernized UI styling for a more responsive dashboard experience.

+### ⏳ Async Demos
+
+If your catalogue needs additional setup before rendering, return a `Promise` from the `demo` function. The dashboard waits for the result before inserting it into the viewport:
+
+```typescript
+public static demo = async () => {
+  await Promise.resolve(); // e.g. fetch data, load fixtures, or await wrappers
+  return html`<my-component .value=${'Loaded asynchronously'}></my-component>`;
+};
+```
+
+The same pattern works for page factories you pass into `setupWccTools`, enabling asynchronous data preparation across the entire demo surface.
