@M0nica Ah, since we're no longer leveraging the button in the footer we can remove the import for ModalFooter! Hooray for deleting code 😄 - I'm going to just leave this one comment here, however it applies to all files in the PR.

It looks like there's a couple files that are no longer using Button as well!
