Here's an example of a paragraph with a SuperNote. SuperNotes are like regular footnotes turbocharged with JavaScript, so they display as tooltips in modern browsers, and remain accessible elsewhere.

This next note is shows on click and is always pinned.

You can also position relative to triggering links.

Finally, here's a click note that's positioned inline.

This appears onclick, and remains visible until you click outside it.
X Hello!
This is your note content. Notes can contain embedded notes too!
This is a nested note. You can nest as many levels deep as you want!
X Always Pinned
This note must be manually closed.
