And if so, what would they like to know?
Ideas:
Designwise: How to make your own tilesets, how to match colors, how to use decoration in a good way, how to reduce mapsize, how to find good tilesets/mapres, how to do background(para x and y etc.)
Gameplay: How do you map a part( for example start with a simple part and add more and more?), How you structure a map, How you make a map that people like to replay
In general: maybe explain every tab: what is proof, grid, brush coloring, pos x,y, Clipping etc.
