Yeah actually I would love some sort of "NPC Creator Tool" either as a built-in aspect of the mod menu or a secondary widget that helped automate a lot of the process of building new NPCs into a downloadable mod. I'm sure that would be a pretty significant departure in terms of the road-map though so I don't expect a feature like that any time soon, if at all. Unless an extremely competent and generous mod-maker wants to make a third party tool for that themselves lol.
