>>2845932Yeah, I did that because it was in the original rig but you left it out. I've used that bone in quite a few projects since 2021, including unfinished ones, as a local arm rotation parent (and then the rotation parent of IK arm+ after introducing the IKs). Thought of moving it back to where it was originally—after the regular shoulder bone—but there's no free spot there, and I'm reluctant to make the rig even more complicated.
