This change is insane. It's one thing to change a layout feature subtly, or to add another layout option. But to have one list option is horrible. I loved being able to see all my stacks and even have stacked opened and be able to see all notebooks on one screen. Now I have to scroll and scroll and scroll and try to figure out what notebook was in what stack. This is a very upsetting update. Reconsidering paying. If layout options are taken away and I now have to scroll forever to find what I'm looking for, then it isn't worth it. I have about 50 notebooks across 20 stacks and hundreds of notes. Just pitiful.
