### Technical

- SQLite database stored at `~/.config/mio/cache.db`
- Can be compiled to a single executable (mio.exe)

### Known Issues

- Multi-select uses double-click mode, not as intuitive as keyboard shortcuts
- TypeScript type warnings (bold attribute, etc.)

### Build

```bash
npm run dev    # Development mode
npm run build  # Build to mio.exe
```

### Keyboard Shortcuts

- `Shift+Arrow` - Select text in edit mode
- `Ctrl+C` - Copy selected text (in edit mode)
- `Ctrl+D` - Exit application
- `Esc` - Exit application (alternative)
