My students have a bunch of very short assignments due today, so my To Do list on my homepage has a lot of items. every time I click on an item to grade it, it opens in a new tab. If I close the tab when I am done grading the item I go back to the Home page where I was working but the To Do list isn't updated. I can click to go to the Home page from the assignment I just finished grading but then I have multiple tabs open.

How do I fix this?
