I am currently working on improving the ergonomics of the H5P Drag and drop question type. Which leads me to have a closer look at Moodle's own Drag and drop onto image" question type. I have already posted on the topic here. Now I have 2 questions/suggestions.
1.- Editing a Moodle D&D question, after inserting a certain number of Draggable items and Drop zones and saving that question, I do not see an option to remove some of those items and zones.
2.- When editing a Moodle D&D question, a teacher can preview the question, and can "Fill in correct responses", which is very useful. However, if a Quiz's Review options's "Right answer" option is checked, the student only sees the feedback message : correct/incorrect answer. I would expect the "Right answer" option to work the same as in Teacher edit mode, i.e. move all the draggable items to their correct drop zones.
