When using the large classes option in canvas and grading discussions, opening the speed grader tool from the group discussion thread opens only the first group. Grades must actually be accessed first through students individual posts.
While not something that makes the system entirely unusable, this has let certain TAs overwriting other TAs work thinking they are grading their own sections.
Additionally, speed grader should have an option to switch between graded groups without exiting the application.
