damnit!! hopefully then something better is implemented into the base game then, or someone figures it out for a mod... for now i guess i'm just going to do what Early Mod Toolkit does, but manually (swapping out my mod folder for another one) until something simpler comes along. i guess i've just been really pampered by the way the minecraft TreeLauncher works XD (it has various modules you can reuse for profiles rather than duplicating files needlessly), but seriously though like all i need are those checkbox profiles...
