I would like when the developers make a tutorial video. People who work with this tool all the time show us what can be done, what cannot be done, what were the problems they faced most and what strategies did they use to solve those problems. They also make a small map with a small quest and explain what they are doing and why step by step.
That would be better, but they can't even do that, because they haven't even reached the "make it usable for non-Larian developers" stretch goal yet, never mind started the re-design. So any tutorial videos they make now will be useless by the time we get our hands on the new-and-improved toolkit.
