I have a suggestion and, after speaking, with Tim about it, he said that it would be possible and a small task. He advised me to put it out there and see if anyone would be interested in building it - he would advise and implement the change.
I have the question type plugin for dragging and dropping onto an image. I love it, but there's one thing that would really help me and anyone else who just doesn't have time to implement the workaround.
Issue: This involves an image that needs to be labeled. Our company has hardware and the technicians need to identify parts of that hardware. They would drag and drop the labels. However, if they get it wrong, nothing tells them what the correct answer, and a trainer may not be present to do so (if they're taking this test remotely).
Workaround: Take a screenshot of the image with the correct answers, and place that in the general feedback, but a) if they get it right, that would always display, and b) it takes time to do all of that (granted, not a lot for one, but for several, it adds up).
Request: The image with the correct labels (text or graphic) appears if they get it wrong.
