This is surprisingly usable in the current form. Nice! Features I would like to see: 1. Select walls and move them 2. Select a set of lines and change the scale 3. A few different line types - adding double, wavy and thick would help a lot 4. Change line color. 5. A "gametime" mode where the drawn lines are temporarily immutable but tokens can be easily moved around. Flipping between the two modes should be a single click. 6. Change background color of grid squares - this gets you forest and river and mountains, or bushes and streams and rocks.
