Allow the older version of the assignment/to-do list to still be used.

The updated setup basically forces you to use the donut or the standard canvas to-do list. Bring back the old options of being able to turn on the 24-hour clock without the donut, being able to cross off assignments, being able to add assignments under a class and separating assignments and announcements. I know a lot of people like the donut, but not everyone does and losing the ability to set up the list this way really just defeats the point of Better Canvas if you don’t like that setup.
