I am not particularly experienced at making user interfaces,and my main concern is the interface could get cluttered up and become hard to navigate as more and more exercises are added to an exam.
Here are some screenshots of the app, followed by a brief video showing how it's navigated in a browser. I apologize for some parts in which language gets mixed up, that's for unrelated reasons.
A few issues I've identified with this interface:
As more and more exercises/questions are added to an exam, the size of the content on the screen grows very quickly, making it harder to navigate from one item to the next one.
Questions are displayed inside the editor in the order they were added, and there is no way to move them around. The reason being, if you turn off the "randomization", the questions will be displayed to students during the exam(s) in the order they were added, so the order they are displayed in the editor is not just cosmetic but also has a function.
To manage topics, you have to jump back to the list of topics, and I don't know if this can be a problem as far as user experience.
A solution I've thought about is to add an index that shows questions/exercises grouped by topic. That would give the teacher a logical view of the items. The index would have links to jump to the specific editor for the clicked item, and it would be always accessible -- think an icon at the bottom right that expands into this menu-like index upon clicking.
Another solution would be to actually allow teachers to move items up/down the list, but that would also cause an effect on functionality, i.e. the order they appear in the exam would change; at that point, I could add an explicit "ordering" number in the editors that would decouple the position they appear inside the editor from the order they are presented in exams. I'm afraid this would have the opposite effect and make the interface more complex and hard to use, though.
I'm looking for feedback regarding the three points I raised, as well as any input for solution I might adopt.
