Is your feature request related to a problem? Please describe.
Change the advisory banners that appear over the title when page is published, updated or when there is an auto-save warning etc. This UX implementation looks clumsy and doesn't fit with the general look of the new block editor

Describe the solution you'd like
Something a bit more subtle elsewhere in the interface. Something dynamic like if you temporarily displayed in the top bar over by the Preview / Update buttons. Or, even if the the View Post item in the admin did some sort of subtle highlighting to suggest that should be clicked.

Describe alternatives you've considered
Sorry if I don't have any concise suggestions but I think that the new block editor needs a little bit more polish here and elsewhere.
