## Recommendations
### For Developers
1. **Always test on target platforms** - Window Manager features are Windows-only
2. **Use platform detection** - Check `platform_detector.py` output before assuming features
3. **Implement fallbacks** - Graceful degradation tested via `service_fallback` plugin
4. **Validate payloads** - Use `webhook_validator.py` before sending webhooks
### For Users
1. **Install optional dependencies** for full functionality:
```bash
pip install psutil easyocr aiohttp paho-mqtt
```
2. **Linux users** - Install xbindkeys for enhanced hotkey support
3. **Windows users** - Enable long path support for best compatibility
### For Testers
1. Run all test plugins before release
2. Test on all supported platforms
3. Verify graceful degradation works
4. Check webhook payload validation
