I was playing ksp the other day, and was trying to perform an EVA from my space station. I did what I wanted to do but failed to bring my Kerbal back into the module. That's when it struck me. I thought that tethers should be implemented in the core game. They are such a vital part of real life EVA's that I thought that it would make a lot of sense for Kerbals to have them. I dunno though, what do you think??
