In the test section it would be very welcome to have questions where it is possible to drag and drop items on to a specific section of a picture. For example: I teach music and it would be very helpfull if students could put given note values on a staff where they have to ad the notes to a certain pitch. Or put ties between notes. It should be possible. At least it is a form that was used this years exam on music in The Netherlands, made by www.Cito.nl.
