PLEASE create an UNDO button for the "Scores by Class" page and the scores by "Assignment" page.
When entering scores by class, if you accidentally hit the space bar while a student score is selected, that score is gone forever! Also, when entering comments in the scores by assignment page, it automatically selects the entire comment and can easily delete the entire comment when you just wanted to add something at the end.
How is it possibly 2025 and we don't have an Undo button?
