UI for editing Instructors/TAs is confusing #61
Description
The UI for adding course staff is confusing. You can only edit the username, but the name text box looks like you're supposed to fill it in.
I'd suggest graying out or even hiding the real name field, and changing the plus button to like "lookup and add" or something since it works differently than the + button at the top of the menu. Maybe it would be best to pop of a modal to take the username to completely separate the "add new staff" UI fro the "display current staff" UI.
