Currently, if we create a page that is Modal or a Drawer we can add regions to the footer (eg: Button Container), it would be nice to have such functionality in the inline versions.
In most cases I can simply swap them to a page, but I've got a few examples where they are part of a form that the user opens for inputting additional information.
This is more for the aesthetic then actual functionality because the button are there, just not at the bottom/footer.
