When assignments/ quizzes/ things get stacked, I hope Canvas could show or notify me which assignment is going to overdue before 1 hour of the due time. This could help me to track the assignments process and make sure everything is done properly.
Also, for the quiz section of one course, show "completed/ graded/ processing" status just below the title of the quiz could make life easier. I can check each status easy and fast, instead, I have to go INSIDE of the quiz page and see which one is done, which one is not.
I really hope these things could be improved!!
