How do the additional SpeedGrader quick links work with Large enrollment grading: Launch SpeedGrader filtered? I assume for courses that use that, they'll need to continue to use the longer workflow to go into the assignment where the drop-down list of groups appears next to the SpeedGrader link. What happens if they enter SpeedGrader from one of the other new locations without selecting a filter first?
EDIT: I have tested this. NQ SpeedGrader, with this, does work with the "filter by group" choice. However, it requires the user to go to an assignment or the gradebook to choose the filter first. This is comparable (sadly) to the CQ behavior (that also required selecting the filter before SpeedGrader for a quiz), so no enhancement; just parity.
