idk why we don’t have it at least confirmed, if it’s because were all scared of everyone making vulgar gestures with their arms, well here’s some suggestions:
a great number of vulgar gestures are done with the hands, so, have presets for the hands. my suggestions would be:
open, flat out palm
the “rap hand”
use that and you don’t have every jita alt giving you the finger when you go to read your bio. I know one other common gesture is that one, where you take your arnm and kinda form an upsidedown “T” with your elbow, well, i’d think if you stop the arm from coming out at that angle, you can grant full range of motion of the arm, but stops from making that particular gesture.
