It would be great to be able to sort assignments by grade earned on the assignment pages and the individual student roster pages. It would also be helpful to be able to sort by final grade and attendance on the roster and gradebook.
This would allow you see all failing grades grouped together and make it much easier and more reliable to manage rewrites and extensions. The list of assignments gets extremely hard to read when you have more than 10 assignments in the course, and it is too easy to overlook failing assignments.
There's no good way to use Ctrl + F to try to highlight the failing grades, either, because that text is not unique enough to stand out on the page! Maybe this could be be a highlight feature in Populi that highlights any failing grades?
There are a lot of feature requests for grades that are tangentially related, and I appreciate this detail also being considered!
