I hope this is the right thread for this questionn, becauae I can only explain my wish xD
I need a addon that activate/load or deactivate/unload addons, but not by char, this functionis already given by WoW. What I need is to have several, let's call it "profiles" for one char. As example, one for Raiding, one for Questing and one for administrationi of the guild.
Currently my workaround are 3 sets of "Interface" folders, but I'm not really happy with this.
