Hi! Thanks for the feedback. To be honest even I had forgotten that you could reorder the columns, though I think it could be useful sometimes. The tooltip idea sounds fine. And about the license, like all blender addons, it’s gpl, but that doesn’t mean it’s free as in free beer. It’s a commercial GPL addon. Here’s a thread about this topic in case you’re insterested: Commercial GPL Blender addons and the copyleft?
