Feat Request: Settings Export

[DevGuyRash]

Thanks for creating this! It's been amazing on the Steam Deck which tends to reset yay installations and anything installed by pacman on an update.

I've been forced to rely on appimages ever since and appimagelauncher has too many issues with arch for whatever reason (no hate there though).

I would like to set this up on several steam decks and would like to request the ability to import/export setups for appimages (even if they're not installed yet. Ideally you'd be able to change the executable path after the fact).

Even just individual exports for appimages would be great!

Thanks again!
