Action Bar troubles
 

Recently it seems my RDX keybindings don't transfer well between possession bars and spec changes.

When i change spec, my main bar changes, but my keybindings remain bound to the old bar until a ResetUI(). Similar effect is observed when i mind control something.

Also, while we are at a question of action bars, is there any way to show / hide individual buttons, based on mana, range, cooldown? Not necessarily disable clickign on them, just make them invisible.
