You are an instructor. You see a list of ungraded assignments. You see three ungraded proposals, and two ungraded journals. You grade the proposals and when you have graded the last one, Canvas automatically takes you to the next batch of ungraded assignments, in this case the journals.
The button that takes you to the next ungraded assignment in speedgrader would automatically take you to the next ungraded batch of assignments in the course, so you don't have to leave speedgrader, go back to the dashboard, refresh to remove the graded work, and then click on the next batch of assignments.
