Just an idea... it would be really great if there was some mechanism whereby you could remove "earth", such as a meteorite crater rim that is just barely in the way of come much needed construction. For example, I needed to make an exit, and I placed two airlocks successfully, then went to add a ramp, and it barely made contact with a meteorite crater rim... no dice! Again, not a show-stopper...
