In order to make life of an Grader easier, annotations can be reused. I.e. while creating a comment it can be marked for reuse. When a comment is marked "reusable" it will be stored in a common "annotations-pool". When creating a new comment the Grader can either select a fitting comment from the "pool" or create a new one. Reusable comments should not be deletable in any case.
- Try to delete a reusable comment which a peer Grader or the instructor created
- Test if non-reusable comments don't show up in the reusable comments list
* What if a Grader tries to get familiar with the system and creates a reusable comment, without knowing that they will not be possible to delete? Maybe make a reusable comment only deletable when no references to this annotation exists or if the Grader is the "creator" of an annotaion?
