not sure if this question or discussion already exists but...

When students make a comment on an assignment submission - especially AFTER the assignment has been seen and graded by the instructor - is there any way to KNOW such later comment has been made other than just Canvas emailed notification? That does not seem very effective to be sure we catch all student comments made after the fact. 

It would be nice if there were some clearly visible notification in the course site/grade center: a colored icon or at least a notice in the course home page (with the list of other notices re: submissions and such).
