In the Speed Grader, when I'm viewing assignments that have multiple files uploaded, there is no indication about which file I'm currently looking at. Please incorporate a marker (title on the viewer page, or an indicator on the file names) so we can better keep up with our place in grading.
A newly selected file is highlighted only until something else (like the annotation tools or a rubric or the comment box) is clicked on.
Screen shot is provided to show what the files look like. Having to go through and try to figure out where I was each time I need to move to the next file is not a productive use of my time.
