Issue: In Overlay option "Merge existing secondary groups of user with new groups" should be controlled by a new permission if user is able to see/use this option in overlay. because at the moment when my moderator only should be able to control 3 of all 10 secondary groups, he can only select these 3 secondary groups how it should, but if he activate "Merge existing...", then the edited user will be removed from all 10 secondary groups instead of only the controlled.
"Notification via: Email" is it possible to only show alert (controlled by a new permission) as option?
