The upshot of this one is that the whole purpose of quick-grade gets undermined if you have to keep flipping back and forth between pages just as if you had clicked the "grade" link on an individual assignment in the first place. Is there a way to make the spy glass next to the online assignment submission trigger a popup instead of a brand new page? That would keep the workflow less onerous when grading a huge bank of submissions. That is also what we were used to seeing it when grading online assignments in the past, and it worked pretty well. I don't think Jon is trying to get the assignment submission to appear in the submission column--that wouldn't work with all of the other column scroll issues you are working on right now. I think we just need to not have to click back and forth so much.
As an aside, Jon, I did note something I didn't know before (as I'm still doing my real grading in 2.2): When you download all assignments (a feature available if you enable file submission on that assignment) you get html files for all assignments which might provide a livable workaround for now--not an optimal one, but an okay workaround, as you can then control where/how you launch the assignment html windows (though tracking that is a bit tricky, too, as the filename identifier disappears when you open it so if the kid didn't put his name within the assignment itself, it is hard to see who did what).
