When will Canvas create an indicator in the grade book that will let teachers know they made a comment on a student's assignment. For instance, I made a comment on an assignment but when I look at the grade book later all I see are cells with numbers, it would be nice if there was an icon like a triangle in the corner of the cell indicating I made a comment on that particular assignment. I get the cells change color for late, missing, excused, etc. but a visible indicator for comments at first glance of the entire grade book would save so much time for teachers.  I tried attaching an image to show a zero recorded for a student and comments made that because the student was counted truant a zero was recorded. Here is where the icon a triangle maybe in the top left or right corner of the cell indicating comments would be helpful.
