**Total: 28+ views across 7 categories**

### 2. Interactive Features
- **Collapsible Categories**: Users can expand/collapse each category
- **Search Functionality**: Real-time filtering of views by title
- **Active State Highlighting**: Current page is clearly highlighted
- **Icons**: Each view has a unique, semantic icon
- **Tooltips**: Hover tooltips with descriptions for all views
- **Sidebar Collapse**: Full sidebar can be minimized to icon-only view
- **Persistent State**: Collapse states and sidebar width saved to localStorage

### 3. Accessibility Enhancements
- ✅ Proper ARIA labels on all interactive elements
- ✅ aria-current="page" on active navigation items
- ✅ aria-describedby linking for help text
- ✅ Semantic HTML structure with proper landmarks
- ✅ Keyboard navigation support (Arrow keys, Home, End, Escape)
- ✅ Focus management and visible focus indicators
- ✅ Screen reader friendly search and navigation
- ✅ Proper role attributes (navigation, list, button, etc.)

### 4. Visual Enhancements
- Category headers with icons for visual organization
- Color-coded active states
- Smooth transitions and hover effects
- Proper spacing and alignment
- Responsive design that works with sidebar collapse
- Progress bar for project integrity status
- Badge counts for navigation items

### 5. Bug Fixes
- Fixed duplicate route URLs:
  - `Impact Analysis` now uses `/views/impact-analysis` (was `/views/dependency`)
  - `Traceability Matrix` now uses `/views/traceability` (was `/views/wireframe`)
  - This eliminates React key warnings and ensures unique navigation paths

## Key Implementation Details

### View Organization Strategy
Views are organized by development phase and domain:
- Planning & Requirements: UX and feature definition
- Development: Implementation and architecture
- Testing & Quality: QA and validation
- Project Management: Timeline and coordination
- Analysis & Tracking: Impact and dependencies
- Security & Monitoring: Safety and health
- Configuration: System setup

### Search Implementation
- Case-insensitive filtering
- Real-time query matching
- Filters across both items and categories
- Clear empty state messaging

### Performance Optimizations
- useMemo for filtered groups (prevents unnecessary renders)
- useCallback for event handlers
- Lazy rendering with scroll area
- Efficient state management with localStorage

### State Management
- Local component state for sidebar width, collapse state, search query
- localStorage persistence for user preferences
- Router params for active page detection
