First of all, love this addon.  WoW wouldn't be the same without it. 
One thing that would make my experience alot better is if I could "save" a spec into oqueue.  My MS is resto but when I farm rep, coins, ect. I do it as tank/dps.  Would be nice if I didn't have to stop and switch specs and gear to join a que as a healer.  Or be able to que as a healer/tank.
