Moving the autosave notification outside the block editor canvas

[CreativeDive]

I saw a comment of @mikemcalister on X about the annoying "autosave" notification box inside the block editor. He is absolutely right and that's why I created this feature request.

Each time when I use or reload the editor one of the first things I do is to hide the notification box. It's annoying and should definitely be changed.

Another place shoud be choosen for this type of notification, e.g. like this location:

... more details could be displayed by displaying a popover when the user clicks on the message box.
