Add a backend that lets users sync their settings between devices. Since Lunar Client profiles, settings and Minecraft options are all saved in plain text, it's possible to save them on a server or CDN and add synchronizing capabilities directly to the client.
There could be a new Cloud or Sync tab in the Lunar Client settings "modal" in-game (where mods, profiles, performance options, etc. reside) that lets you optionally enable the cloud integration and sync from or to the cloud.
I'm suggesting this since there's people who use multiple devices (e.g. desktop and laptop on-the-go), or reset their computer multiple times. Backing up options, settings, and especially LC profiles (since paths aren't documented) can be really difficult, especially for your average player that has no technical knowledge.
