Hello, i initially came here for the same request.
I absolutely love Evernote, but this new notebooks view is a major step back !!
I have more than 50 notebooks, a 24" screen, but i have to scroll 5 times the height of my screen to see all my notebooks.
I used to have all my notebooks immediately available without scrolling before this update.
Another thing i would like to say, is that i realized now i have no idea whats the first character of the notebook i'm looking for. So i even don't know where to scroll to. I think my brain used to record the column or place where things where.
