Fenril, I think the point is that the OP wants to load differing sets of addons depending on the character set. So lets say my Drood1 is my leatherworker and doing auctioning, he is dual specced into resto and feral.

In my TSing character set I want to enable auctioneer, TSM, Lil'Sparky, etc., when he is in the PvP set, I want gladius, recount, etc. to load, but not auctioneer, TSM, Lil'Sparky., when loading in my PvE set HealBot should be loaded, but not recount, TSM, Auctioneer, etc.

The current and builtin functionality allows the user to enable/disable addons based on characters, not "use".

It's actually a neat idea..... Maybe I should try something like this to see if my fps improve....
