• Adjusting your Osu! Keybinds and Settings without needing to launch the game.
• Downloading Beatmaps and Skins directly from the app. (WIP)
• Running repairs on your Osu! Client.(WIP)
• And more features to come

This idea originally came from wanting to have a way to unify everything without having to launch the game every time to change the most minor setting.

No it does not and we do not condone that in anyway, Beatmap downloads are gotten from trusted mirror sites.
