I've just noticed a slight problem with automatic backlinks.
They use ### or <h3>. You can use a span or style element, but using a header element messes up a note.
Imagine you don't use any headers/sections in a note, then a backlinks section looks like this:
Using any h? is a bad idea. Imagine someone using 2 or 4 levels. Why is the backlinks section on level 3? It also messes up the TOC. Please consider using a span or style element instead. Nothing prevents you to use a similar style as a h3 element. Just using the element itself is problematic.
