Instead of being able to teleport to rooms only, how about to specific coordinates? Or even to SCPs? Or even SCPs to you?

I'm not sure if the SCP status could be similar to what you're asking for, as I haven't checked that out, personally. But I think one teleporting feature that would really help is a legend of all possible room files, what they are distinguished by, and if they're in the specific seed. It's pretty confusing searching for a specific room, only for it to be randomly hidden amongst one of the dozens of 2room___ maps.

Well, the coordinates sounds like a good idea. However, a lot of coordinates will leave you out of the map.
