City Maps??

I think this is similar to another suggestion, but not sure. This tool has great potential for Full City Maps. Basically create houses and shops of different types/sizes, hospitals, castle building, farms, ruins, etc… I am sort of doing this already, dog houses for "houses", Items as indicators for shops; but I think we can do more with this. Granted it's not a "dungeon" but who says a city can't be a dungeon for the escaping criminals running from the guards?
