I wish it were easier to organize stacks and notebooks.
I love Evernote, it's a big part of my life. But I wish organizing notebooks would be closer to how macOS's finder works.
I have hundreds of notebooks. When I go to the Notebooks view, I can only view 8-10 stacks/notebooks. The lists are super huge and take up a ton of space. When I want to organize them, I dread it and usually don't bother. Also, it'd be nice to be able to have more levels of organization than just stacks and notebooks.
In the macOS finder, I can create as many folders as I want. I can also choose how the lists are displayed, making it super compact or not. It'd be great if Evernote for Mac could move closer to that.
