First off, awesome modpack, love it and a huge kudos for the amount of work you do keeping it updated for each patch!
I sometimes need to be able to switch between two installations of my mods and thought it would be nice to be able to 'save' several configs in the installer. Any chance it could be possible?
Custom Installation 1 - contains the mods: Alpha, Bravo, Charlie and Delta.
Custom Installation 2 - contains the mods: Alpha
PS. If already possible, feel free to flame me (and show me in the right direction :) )
