I know this is somewhat outside the gradebook project but it would be helpful if the colors for late, etc. persisted to the speedgrader. OR if you could get information about how late an assignment was by hovering over it in the gradebook.
You're correct. This is outside of the scope of this project, but definitely great suggestions to consider in the future. These may be something you want to hold onto and submit as new ideas in https://community.canvaslms.com/community/ideas?sr=search&searchId=60622051-25c3-4e2e-8deb-5d8dce5ce..., once the phases of the new gradebook are generally available - just because you'll have a larger audience then!
