Notifications in Admin HW Folders

As an AT/Teacher you have to go in and check the homework folders regularly to see if there are any new assignments and - especially as a teacher - you have to click through all three of the categories. It would be really helpful with a small notification next to each button (like the one next to the next to the changelog) saying how many assignments each folder contains (or alternatively how many new/unread ones). 

Not only would it help save time, but also give a better overview of the work that is to be done. 

Though this is a small thing, it would really help my everyday WoP life!
