Not really. It depends if our philosophy is “full screen” (as it’s named today) or “focussed writing mode”, which seems to be intention as you say.
I do agree that the double ‘create’ click is a tad annoying, and I’d be personally happy with just full screen, without the focus design.
Haha, I mocked something up like that way-back-when but it’s a big cheese move so it didn’t make it (yet!)
