I would be great if the course viewing filter could be enhanced so that users could select a specific set of courses that they want to monitor and save the view of these courses. Then courses that are in danger of being cancelled due to lack of registration could be dealt with quickly and enrolled students and the instructors could be informed quickly (and en masse hopefully) if their course has been cancelled.
If this capability was given to the Academic Admin, Registrar, and Staff roles, then Department Heads could monitor the courses that students in their programs take for a specific term.
