Thanks for the feedback! I find it interesting you call it a hallway tool, I've never heard anybody refer to it that way before. When I first started, I had the free form drawing, and loads of people were requesting snap to grid options, so I added that as its own tool cause it had a few options specific to it. I personally use it to draw entire maps, as I often find it quicker to fill in a room than switching to the room tool and back. That's how I ended up with that name, and why I feel something like hallway is a little bit too specific for what it does.

I based the wall tool off of the line tool, since I assumed straight walls are the most desirable for people. How would you suggest making it work more similar to the snap to grid tool?

Thanks again!
