Thanks for pointing out that I was missing those commands. How did you find them if they weren't documented?

I'm not sure what you guys are wanting me to add to admin_lookingat. Do you just want the spawnflags value?

I like the toggle freeze command and the snap to grid idea.

I'm not sure if this is what you mean with the spawnprop issue, but you should be able to spawn something in a frozen state by typing frozen after the name of the prop. For example:
Code:
e_spawnprop blastdoor1 frozen
