It would be helpful if administrators/students could sort courses on their Registration tab by the headings already available: Name, Credits, Primary Faculty, Openings, Schedule, Enroll, Audit., etc.
If a student or I could just click the Openings heading and have all the classes that are open (not red) sort at the top, it would prove easier enrolling. (I have noticed students already trying this by clicking headings when I have sat down with them).
