Multiple choice detection improvements
We see some interesting behavior for the autodetection of multiple choice options. For example, these nicely marked multiple choice options do not get recognized, while less nicely filled out boxes do (see below). In general, it seems fully filling squares does generally not get detected, but partially filling it does.
If this is intentional, and Zesje wants "crossed" boxes rather than fully filled ones, perhaps then this could be explained on the front page or when creating a multiple choice question. Otherwise, perhaps it can be tuned to also accept fully filled boxes.
