So far, you can only link one note to another. But you can't:
Link one section of a note to another section of a note
Link one section of a note to a section of another note
EXAMPLE: Literally any wikipedia (<-- random example) page. After the intro description, there is a 'contents' box that links to itself later in a document. You can also click to links of sections of other pages on the site.
OneNote already has this feature. I find OneNote awful BUT this feature is the one and only reason why I use OneNote over Evernote at work, and Evernote just for personal use.
Please update your linking features!
