Dan Sheffler has developed an interesting approach for note-taking in Sublime that is modeled after Luhmann's Zettelkasten. While he writes everything else in markdown, he has developed a plugin to make links by enclosing them in double brackets "work in Sublime Text. You can get the plugin on GitHub."
I also like his way of splitting longer notes by creating "new notes that branch off the parent note by adding a hyphen to the original name. For instance Plato - Psyche.md is a child of Plato.md."
