Pitheco - I'm no modder myself, but I wouldn't be surprised (if the editor is as powerful and user-friendly as promised) if this kind of thing is added later. Good point.

Still, I really hope at least the simple-ish UI fixes listed in this thread's OP that have been frequently requested on the forums (e.g. consistent item stacking, a key ring, inventory sorting, keyboard hotkey selection and toggling, etc.) are implemented by Larian before final release. Fingers crossed...
