It would be excellent to have a way to filter assignments by "resubmitted" instead of having to scroll through looking for the tiny blue icon. This isn't that big of a deal in regular classes, but we use Schoology for professional development across the district, so every time a teacher resubmits something we have to scroll through 1200 names looking for a tiny blue icon.
Alternately, it would be nice if the resubmission link (e.g. "4 resubmitted assignments" on the right of the Recent Activity page) would display ONLY those assignments when clicked.
