A tweak I am eagerly hoping for is to have some sort of shading to indicate when a grade is unpublished.
Sometimes I want to commit a score (so I can see the grade impact) but perhaps I'm not ready to return it yet (maybe some students haven't taken it) so I don't want the grades to show up to the students. Now, I have to make a point of remembering that the grades are unpublished and go back later and publish them.
It would be nice to have a visual reminder when what I see, and what the students see, isn't the same.
