Known Limitations & TODOs

AI Studio

• Mock llm responses: Need to connect real LM Studio API
• Mock model list: Need to fetch from /v1/models
• Simplified JSX transformation: Need Babel for production
• No syntax highlighting: Add Monaco or Prism.js
• No export functionality: Add download button
• No session persistence: Add FoundationDB integration

workspace Tab

• Placeholder only: Need to implement V4 Unifiedworkspace migration
• File explorer: Not implemented yet
• editor tabs: Not implemented yet
• Bottom panel: Not implemented yet

General

• theia integration: Need theia server running on port 3000
• Avatar upload: File upload not implemented (URL only)
• Settings persistence: Currently localStorage only (no backend sync)
• Error boundaries: Add React error boundaries
• Loading states: Add skeleton loaders
• Unit tests: Need test coverage
• E2E tests: Need Playwright tests

---

Next Steps

   • Add Babel transformer for JSX
   • Add syntax highlighting
   • Implement code export
   • Add loading skeletons
2. Testing:
   • Write unit tests (Vitest)
   • Write E2E tests (Playwright)
   • Test on different browsers
3. Deploy to GCP:
