agree with your points, but damn, resolve has some strange UI patterns / key combos etc compared to other software i've used.
maybe if you're a video editor coming from years within the field, the metaphors make sense? for me, having mostly done audio stuff, it was a bit of a journey.
i dont think an onboarding thing would be the solution, though
If you haven't done it, I really recommend the official resolve training:

The UI patterns make a lot more sense after watching the people who designed it explain how it works, how to use it and why it was designed that way.
