+- [x] Add comment/meta text field (below snippet list or in sidebar)
 
 **Deliverable**: Complete basic CRUD with auto-saving drafts
 
+**Key Achievements**:
+- Implemented comprehensive snippet selection with visual highlighting
+- Connected "New" header button to `createNewSnippet()` function for easy snippet creation
+- Added right-click context menu for snippet operations (Rename, Duplicate, Delete)
+- Implemented auto-save functionality for both spec changes and comment field edits
+- Added comment field that appears when a snippet is selected and auto-saves changes
+- Created intuitive UX with proper state management (hiding/showing comment field)
+- Added confirmation dialogs for destructive operations like delete
+- Maintained consistent retro styling for all new UI elements
