True story: a couple of months ago, a teleport error accidentally brought Stoot into a role-playing session that some friends and I were enjoying. With no prompting, Stoot immediately apologized for the fact that we couldn't sit down to play. (There are photos!) So the team is definitely aware that this is a problem.
The stuff our glitches can do, and colors, appearances, clothing, etc, is very tightly coded. Much work has gone into optimizing it. The set of things our glitches can do is very well thought out. "Sitting" is a Glitch 2.0 feature- they would almost have to start over to add it. Let's let them finish 1.0 first.
