This is from a new user's perspective.

It might be helpful to others too to explain some of the features on top of just describing the keyboard shortcuts. E.g. what does the "Tileset" window really do? Why and how should it be used?

I'm currently developing my first game with bigger maps using VChar64 and have a bit of trial and error figuring out what does what and why. I can offer to help adding more documentation as soon as I understand it all completely, if that helps.
