What happens when I delete a wall?

The room stays, with an open side where the wall was. It keeps its name, its purpose and its size, so you can open two rooms into one without losing either. Undo puts the wall back.

To remove a whole room, select it and choose Delete room. That takes its walls, doors and name with it, and it can be undone too.
