I know this is a bit of an old discussion, but I much prefer to see my notebooks on the left panel. Not only are they easier to access this way, but I have a long list of tags that I use.
I really hate the view that opens up in just Notes, plus a bunch of stuff I never, ever use - "meeting note" and "work chat".
I am using the web version and there should be a way to go back to this older view.
There are many of us who use Evernote for our creative projects and not in work environments, nor do we work on teams.
