One of the most frustrating aspects of assignment notifications is that when you click the unit or assignment submitted for the student, you have to then click from the assignment screen to get to the student's submission. If you have 70+ in a class, sometimes remembering the name you are looking for means going back to the notification screen. This process is very cumbersome when trying to track the recent grade submissions from notifications.
As a virtual teacher, I really need the notifications to go right to the submission or comment, etc. I think (right now especially) this would help everyone get grades and responses processed faster.
