I would love to have some kind of "picking abality". It would work this way:
1. It ist relevant for all kind of content, which includes other types of content: interactive video, course presentation, ... (I don't know which kind of content are there overall, those are the two I use.)
2. It would allow you to pick any existing content and put it into your new content. Example: I have a course presentation with multiple choice questions in it. I frist create the questions as a stand-alone content, then create my slides and choose the questions, I want to use. This way, if I have two different presentations, but want to use the same set of questions, I don't have to re-do all the work creating them.
3. Optional: It would allow to save any existing content in a presentation or video an create a single-activity out of it - example: it would be possible for me to use my old presentation, save some hotspot activities out of them and then give them to my students while thier exam - without re-creating just the same again and again....
