It would be great if you could put your setups in "folder like" groups(with the option to name them), similar to what photoshops allows for layers.
If this was suggested before, I am sorry.

+1000, it'd make my life easier, same for skins haha.

Maybe it could be done as like creating a normal folder on windows and then LFS detects that folder contains skins/setups and it shows it with the possibility to collapse/hide?. That was my original idea, dunno if its possible tbh.
