The quiz edit page could be improved. One thing I would like to change is the way in which currently changes are only saved when one leaves the page. If one adds a question to the quiz by pressing "Add selected to quiz" or if one deletes a question from the quiz by clicking on the delete icon then one is led to believe that this action has indeed been performed because the display on the page changes accordingly. However in reality the quiz is not actually updated in the database until one clicks on "Save this whole quiz". This leads to two problems:
1) If the teacher navigates away from the page for example by following the breadcrumb links the changes are lost.
2) When deleting a question from the quiz and then trying to also delete it from the category one gets an error message that the question is still used in the quiz.
I think it would be much better if the changes were made in the database straight away. Are there any objections to this?
