I know bumping this is dumb but I didn't want to make a new topic and I found out

HOW TO OPEN/USE THE EDITOR! :D
It's fairly easy to use, just
1: open console (~ key)
2: type "editor"
3: hit console key again to exit the console
4: screw with arrow keys and numpad to move and rotate objects
The only basics I haven't figured out are moving objects vertically and adding new objects, but it's still kinda fun to mess with existing levels.
Still, if we figure this out we could make our own levels :D
