## Documentation

Comprehensive documentation provided in:
- Inline code comments
- Test descriptions (58 test descriptions)
- Component structure documentation

## Bug Fixes

1. **Duplicate Route URLs**: Fixed two views pointing to same URL
   - Impact Analysis: `/views/dependency` → `/views/impact-analysis`
   - Traceability Matrix: `/views/wireframe` → `/views/traceability`
   - This eliminates React key warnings during rendering

2. **Missing Specifications Item**: Added Scenario Activity to Specifications section

2. Custom category ordering (drag & drop)
3. View group templates
4. Usage analytics for view access patterns
5. Recently accessed view suggestions
6. Custom view groups per project
7. Export/import view configurations
