Dropdown for adding user to a group should filter users already added
This is a feature request, and I couldn't find it searching.
When adding users to a group, the dropdown list is not filtered by who's already in the group. It's easier to find "new" people, visually, when the known people aren't listed. Yes, there's search, but sometimes I don't know who's new to the org, or maybe I can't spell their name :)
