Sections within notebooks (like dividers in a binder) like in OneNote (preferably with multiple hierarchy levels)

[JanineHM 0]

I really would like to be able to divide my notebooks with note hierachies, and I came over OneNote because it's actually possible to share specific notes here, and I don't want everyone to have access to my whole notebook. However, I'm seriously considering switching back now I know that Evernote doesn't have the BASIC functionality to actually organize your notebooks into sections! I need to be able to use subsections. I'm trying to reduce going back and forth in different files but if I have to go back and open a whole different notebook to see a note from a slightly different topic that defeats the purpose of using a notes app. It might be better just to use the computer's native file system, because at least it has hierarchical organization!
