As you can see in the pic, I have a notebook that is nested called GTD (noted by the arrow). I cannot recreate this structure! Was it that Evernote used to support nested folders so mine is a holdover from the old days, and now they only have Stacks? I don't like stacks b/c they don't show up at the top like notebooks, they only show up under the tags section. Is there a way to make more of what I have here?
