viewing and changing group membership upon "edit" button of a group / default action
currently, when you "edit" a group", you can change its ID and name.
in contrast, in my experience the most often used action regarding a group is
- to see which users are members of it
- change membership of users
you almost never want to change its ID or name.
in the old UI you had the "members" button for this, requiring an extra click.
in the new UI the edit button could lead by default to the membership dialog, or even combine both (membership info+ID+name).
currently i do not see a way to set any user's group membership from a group's perspective, yet.
