Thank you very much!! I’ve been slowly drafting some ideas for a Ui guide!!
A bit late but my subjective wish for how it would function would be that you can set the screen size, add your own graphics, adjust where you want it on the screen and when you have what you want, you then get the scene tree hierarchy and the settings in the Inspector.
This is very subjective and perhaps idealistic (I think that's the word I want to use) but nonetheless, I'm looking forward to it!
