Lastly, here's another 3 suggestions to Level Editor:
1. Add "Erase" button. Pressing it, will remove some objects and tile when selected. I know that Undo button exists, but it removes previous object, not the selected tile.
2. Add lunch tables. THIS is what my cafeteria looks like in this editor:

3. Some items (like Alarm Clock, Super BSODA and others) is missing in this editor. Maybe you should add them in there
