Hi I think that is a great portable map making tool!
I'm planning on using this for a future session of our Homebrew RPG. I am planning on running it through my laptop and using it as a battlegrid.
The issue is that the font of the characters is really hard to see any I can't find a way to change it anywhere except gray scale (which kills the great colors and atmosphere of the map.
Oh and custom character icons would be great or at least our custom PNG's
