In the old Gradebook, you are able to hover over the total grade column and see [number of points earned] / [number of points possible].
In the New Gradebook, you can view the total grades by points, but there's no way to see [number of points earned] / [number of points possible].
It would be very helpful for faculty members to be able to see at-a-glance how many points are possible at any given time in their course.
