When grading assignments, particularly Discussions, with their multiple nested sections (roster, discussion thread, teacher comments), it's easy to wind up with very little room to see the student-submitted text, even on a large monitor. In the attached screenshot, there are four layers of toolbar/header content above the student text, each of which removes another strip of height from the visible display. I wish there were some kind of "collapse" command for these toolbars, like Office and Google Docs offer, to allot more screen space for the task at hand. Another option would be a "full-screen grading option," where the student text and teacher comment areas of the screen could expand to float over the rest of the BB interface. Alternatively, it would help if we could stretch the width of the student-submitted text in discussions, since most of the right side of the screen is wasted space.
