I appreciate the visual representation of who's in which group in CP > Users > User Groups > TheCoolGroup. The left pane showing all users, and the right showing its members.

But how can I assign members to TheCoolGroup from their user profile?

I have added a type: user_groups fieldset to my user.yaml, but when I edit the user profile in the CP and assign TheCoolGroup group, this is not reflected in the CP > Users > User Groups > TheCoolGroup. The user still appears on the left pane with all the other uncool members.. :(

Am I trying to enjoy the visuals of one thing and the function of another thing, which are actually two completely seperate conventions?
