The Canvas student user's list view dashboard seems to be the only current way for students to see that an assignment has been reassigned. This is not helpful. At minimum, the "REDO" label should also appear on their assignment in Grades. Ideally, students will get a highly visible, prioritized notification that an assignment has been reassigned to them, and a section called "reassigned work" or something like that would appear at the very top of their grades if they have assignments that have been reassigned.
