## When to choose
- you use Linux and want a GUI to configure a supported gaming mouse
- you want an open-source alternative to Windows-only vendor configuration tools

## When to avoid
- your device is not in libratbag's supported device list
- you need configuration on Windows or macOS
- you prefer a CLI or config-file-based setup
