And I do appreciate the effort that goes into it, especially in the latest versions as it got much better,
But I really really really REALLY don't want that UI in anything else other than Blender.
Please don't.
If you're already using Blender to make assets, there's some benefit to stuffing Blender's UI into your game editor too.
It is not a UI paradigm that you would use for just anything, but for certain poweruser software it is one of the best paradigms I have seen, especially since they managed to get rid of 90% of the rough corners in the past decade of development.
But a good design system does the trick. Artcraft apps use this library and their Adobe clones come very close to the original apps.
Q: “Whats wrong with tkinter?!?!”
A: It sucks, that’s what!
That UI is fine to be on many more places than Blender, given that many libraries people use are way worse. Imgui for one example.
