When there are more than a handful of discussion posts, it can be time consuming to grade them given the current features. Especially if one needs to see all of a students posts before grading. The following two features would be a huge improvement:
1. In the "highlight user" dropdown, include a symbol that indicates the person's posts have not been graded (like the orange dot that is currently next to each post).
2. Once a student is selected from the "highlight user" dropdown, provide a "jump to post" button which when clicked would jump to that student's post, and when clicked again, would jump to that student's next post (if there are multiple posts).
The inclusion of these two features would allow for efficient grading...probably cutting the amount of time needed by well over half. So much time is currently wasted scrolling back and forth looking for posts.
