@thenexusofprivacy it's pretty janky lol. i just write either [#fn-uniqueidimadeup] or [#ref-uniqueidimadeup] in-text depending on whether it's a footnote or a reference, and then i put an accompanying [fn/ref-uniqueidimadeup] at the bottom of the page with the footnote/reference content.

then when i'm about ready to publish, i run a little script to go through and grabs the rich-text, changes it to a HTML card, inserts the footnote, and numbers everything for me.
