Links can, of course, be made to headings and/or text blocks. However, when looking at incoming links for a particular note, all links are mixed in together; you have to skim over all of them to see what links to the page as a whole and what links to which particular sections.
It would be great if the links pane would separate incoming links to specific section headers from links to the overall page so you could look down the list and see at a glance what goes to a specific section.
By way of example, a note for a book of the Bible that has headings for each chapter. If you could see “these are the links that point to Galatians, and these are the links that point to Galatians>Chapter 2, and these are the links that point to Galatians>Chapter 3,” etc., that would be much more helpful than just having them all dumped into one long list of incoming links.
