It would be nice if the little checkmarks that are infront of the single lessons when you submitted a homework could indicate whether the homework has already been graded or not.
If it is not graded yet, the checkmarks could be black, like they are now. When the homework is graded they could turn green. As an option they could also be yellow when the grading has started (for example when one or two gradings are already done.)
This way we would have a better overview over the homework status.
