Grade for problem not easily clear
If the marks you give include subtractions for several issues the grade a student gets for one problem cannot be ascertained quickly (you have to manually add 3 or 4 numbers). It would be nice if there was a little box with "grade for this problem" which on the grading page showed the grade the student would get with the currently selected issues.
A different but related is the following: It might be nice to allow us to overrule this calculated grade for the problem. This should not happen often, but if the answer does not really fit the grading scheme it would be convenient if a score can be plugged directly instead of having to make a separate feedback item like "3 points" for such students. (If you have many students with 3 points, clicking this feedback item is easier than manually writing down the grade for each of them, but I notice that in half the problems I create such an item for 1 or 2 students, which is low enough that a plug in the grade box is much faster than creating the feedback item).
