Hi, I am running into a frequent issue with my Speedgrader. For context, students are responding to a discussion prompt + submitting supporting files (mostly notes on assigned videos). But when I open the gradebook in Speedgrader, the viewer window only shows the submitted files. It doesn't open with the student's post and I don't see any way to close or minimize the submitted file in the viewer window itself (see below). If I open each individual assignment in Speedgrader, it does show the students' posts; but when I click through from one student to the next, or select an individual student within Speedgrader, the view defaults to the submitted file preview.
