Can you elaborate further on what you mean by plugin support?
If you mean the ability to write the underlying code to create new APIs, I think that would be ideal. It lets us expand the functionality of the editor for Larian, and they can just add that support at a later date if they feel it's worthwhile.
I'm not entirely clear on what the gameplan is for the editor, or how much of a priority it is. If we had the ability to just fix these problems outselves, I am certain many of us would have already started working on a lot of these things. I know I would be at least.
