I realized that while I could move around as many vertices as I wanted, I had no real way to actually bulk select stuff to move. So I created a nice box selector, which allows me to quickly grab large sections of map and manipulate them.

I also realized that some of my walls didn't exactly line up with the planes that they were attached to. I added a feature into the engine that will automatically check any time the map is changed that these all line up and if not, it flags the wall, which will cause it to display with an obvious purple tint, telling me that I need to either delete the wall or adjust it properly.

I build this nice little fountain area today.
