## Areas of Interest

### Providers
- [ ] Review provider implementations
- [ ] Compare with CodexBar approach
- [ ] Identify improvements

### UI/UX
- [ ] Menu bar organization
- [ ] Settings layout
- [ ] Status indicators

### Authentication
- [ ] Session management
- [ ] Cookie handling
- [ ] OAuth flows

### Multi-Account
- [ ] Account switching
- [ ] Account storage
- [ ] UI patterns

## Action Items
- [ ] Review specific files of interest
- [ ] Document patterns (not code)
- [ ] Create implementation plan
- [ ] Implement independently

## Notes
Remember: We're looking for PATTERNS and IDEAS, not copying code.
All implementations must be original and follow CodexBar conventions.
