I love it. Just a little enhanced and I would use it regularly.

My primary problem with it seems like you can't move a wall after its placed. Deleting and redrawing instead isn't the biggest deal breaker if it's basically a seamless operation.

As a stopgap I would recommend adding keyboard shortcuts for your tools. If I could 1,2,3,4 to activate those buttons or even Q, W, E, R it would I'd probably have used this for a few hours tonight, haha.

Great work, I think this is a waypoint on the path to a really useful tool, thank you for sharing it.
