You know what I like? Interior / Exterior maps. Like this one:
I wish there were a ton of these. I wish more of them didn’t have gridlines already.
But…no. OK fine. I’ll make them, then.
Maybe exports with and without gridlines. Probably an extra layer of roofs with a transparent background, so you could use them if you printed the maps out, or use them as a token layer that can be removed.
That sounds useful.
