Easy navigation between different works of the same student
When a student's answer does not fit on the space provided I hand him an extra paper. This is scanned like the rest and is properly marked (it turns out the student gets the sum of the scores of the two papers he handed in). Sometimes students write part of the solution on one paper and the other half on the second paper. There is currently not an easy way to navigate between the two papers handed in by the same student. Also if you navigate to the student, I can't see how you can choose whether you get to see the first or second paper he handed in.
Thus it would be good if there was a simple button "other paper by this student" (with an indicator whether there is another paper).
