It could be handy/useful if there were little check marks on the side of each section/page of a course page showing if students have visited a section, a page, or have completed an assignment. I believe the gradebook has something like this but only for missed assignments. It might be handy to have a little (green, yellow, blue, whatever color) check mark indicating if students have visited a page or done an assignment.

This could provide a quick "at-a-glance" or progress view of what has been done and what has yet to be done.
