I can't tell you how much I despise leaving Speedgrader, trying to locate assignments in a crowded gradebook, and then having to change a students' "late" marking to "none" if they were absent, receive extended time, or have special circumstances. I have courses with 40-70 students and finding these singleton grades to fix in gradebook takes forever. And then I'm out of my speedgrader workflow. PLEASE just double these in the Speedgrader. Then it would be, you know... speedy.
Maybe there's something that I can't see for some reason, but I would really like to be able to mark students assignments "missing" or "excused" from within Speedgrader. I can do this from the box in Grades, but not in Speedgrader (unless, as I said, there's something in my school's specific configuration that is hiding this). It seems from previous Idea Conversations that this once existed, but I can't see it, now.
