It would be helpful if there was a field in the Questions table that indicates when the question was created and/or last edited. This would allow instructors/admins an easier ability to determine if questions/content within their Exams are potentially dated and in need of review/refresh. It would also allow for them to find the original if they potentially copied/duplicated quesitons.

Lastly, it would be helpful if they could search/filter the list of questions based on the date field.
