Instructors can disable comments on Announcements and have that setting applied to every Announcement throughout the entire course. Individual Announcements can be closed for comments.

Instructors can hide the box and whisker plot (grade distribution) graphs to keep students from viewing the summary statistics of the class and figuring out each others' grades. By default, the whisker graph is on.

For easier grading, you can sort assignments by student name [alphabetically], the date they submitted the assignment, or by submission status. If your course has sections, you can sort Assignments by section.

You can view section enrollments within your course Settings in Canvas.

You can delete a section by editing your course Settings in Canvas. You cannot delete a section with users enrolled.
