Excellent work. At first glance, I'd say this is The Right Way to do documentation for complex GUI design applications.

I hope it catches on, because the lack of quickly accessible/searchable info like this is part of what keeps me from learning new GUI tools. One example is Fusion 360, which seems like a great way to design 3d printed parts. Instead I just keep plodding along with openscad, because it takes me more time to learn one design step in fusion, than to just quickly write up a first draft in code.
