Blender was my first thought here, too.

A while ago, I was asked to write a plugin for Blender since I really liked the program. I looked into it but realized that it was a python-only situation and I really just can't stand coding like that, so I passed on it. But if I could get the python ecosystem without having to code like that - that's a really interesting prospect!

Never looked in to its package size, as far as UI goes, but that does sound like something that could be interesting! I do wonder how different it is from imgui, but there could be something there!
