I think it would be useful to be able to save different modpacks (not mods) into a single file. That way, if you have LOTS of modpacks, you won't need to worry about scrolling through hundreds of mods just to find the one you're looking for.

For example, if you lots of modpacks that make the game realistic, you could make a modpack folder titled "Realism" and store those modpacks in there, that way if you wanna play realistic Minecraft, just go into the file and select the modpack you want to play.

BTW: When I say "File" I mean like what modpacks are in-app.
