Gradebook view shows each assignment in green, yellow, pink or grey. I think it would be great to create a 5th visual distinction to make it possible to distinguish between programs that have been submitted and programs that have been reviewed and passed.
My suggestion would be to add a black outline to assignments that have been passed as this would be consistent with what is done in other areas on CodeHS. If that is difficult to implement in the Gradebook view, a different color (black? blue? different shade of green?) would also work.
What do others think?
