Hi, I have a relatively small system made for me by a member here. What it did was get the last few spells used by the unit and saved them. That way, if the unit casted a spell it could cast it again actively or passively with another button. Or, the last spell used by that unit could be stolen.
I was using AutoIndex at the time. I recently switched to UnitIndexer, and am not sure how to rewrite it for compatibility with UnitIndexer (With AIDs compatibility). It uses the AutoCreate/AutoDestroy modules.
Here is the system in question:
