Three pieces of feedback of varying usefulness to the community:
Suggestion: Annotations done by the instructor for feedback need a Notification students can turn on.
Suggestion: These blue dots should show up in the Grades area so students don't need to click into the assignment to see them. I am under the impression that students who are not seeing feedback are not making it this far then giving up.
Testing observation: The blue dots are appearing inconsistently. I would submit a screenshot, but it is just the absence of the dot. After some testing I am unable to determine why the blue dot will appear sometimes, but not others.
Thanks.
