Thanks for your suggestion it's a great idea for the many RPG tabletop games set in modern day. Right now there is only basic wooden furniture in a fairly generic plank style (Tables, chairs, bed) built into Dungeon Maker Sketch, but you can import your own assets if you wish.
I bought the program. I found it simple and objective. Exactly how I wanted it! When importing a file an error appeared, but in IMPORT the png file was there. How do I delete exceptions?
