Review tests

[TWINGSISTER]

This plugin stores student's attempts. Either ongoing attempt or completed ones. Students have the option to see the attempt but, in the case of completed attempts cannot submit anything after they revised the completed attempt.
Actually the for a multistep exercise the student can only see the last screenshot. Actually the plugin stores the GGB file for the attempt that, inherently, is a construction, so, in principle, the whole process that led to the note is available in the plugin.
This is a good thing nowadays when parents often question notes. So I think that for completed tests students must be allowed to navigate the solution process. Think will bang out some code for this since, looking at the sources, it sounds quite easy to add this possibility. Further more, as a byproduct, I will add the possibility for the student, before sending the test, to annotate it with text boxes, images and freehand notes. This will open the door to revised evaluation and avoid usual (often not grounded) pedagogical complaints about automatic evaluation.
Hints are welcome.
