Enhancement I would like to see

[Schmoe]

I know that some of the other scripting enhancements that were proposed were improved spell selection AI, an option to define certain scripting templates for re-use, and the ability to mark specific spells as "no-cast" or create a pool of usable spells. The devs have said that AI programming is not enjoyable, so improved spell selection AI probably won't happen. The other options add quite a bit of new game logic and data storage. The Repeat Cast option adds a single scripting option (UI code), re-uses existing spell selection code (from Cast a Specific Spell), and adds minor logic to the combat AI. It can probably re-use a lot of the existing code for the Cast a Specific Spell script.

Of course, I don't actually have access to the source code, so all of this is just speculation.
