last night I added a couple more pieces to my space station. Originally I was just going to add the lab piece separately, but then decided I liked how I situated that there with the engine still on, as a sort of escape vessel. So tonight I will get another stand-alone lab to attach that isn't rocket-mounted. Also I like the look of the labs as space station parts, so I'll probably add a few more and chain them together to make it look like living quarters, distinguishing them and the "real" lab by having a bunch of blinky and pointy things sticking off the real lab.
