Room symbols continued: When you use 'z' or shift to hover over a room type, it might be nice to add the room type symbol to the pop-up hover. Or, maybe have the symbols on the room become colorful and easy to make out? I also wonder: Might it make sense to "shift" the room symbols? Like, room symbols are not placed on the center of tiles, but always on the edges between tiles? That way, characters will never stand fully on top of the symbols, even if the room is full.
