To my knowledge there’s not currently a simple way to save notes on Substack … Like if they could add a “star” option to favorite notes then you could go back to your favorites.

I engage deeply with Notes, as you know, so I keep a running Google doc each week of the Notes I’m interested in sharing and commenting on further. If I were a spreadsheet person, I would probably create one with a link directly to the note and a short message to myself about what the note is about.

The only other option I can think of is to go directly to the note and then save it as a bookmark in a favorites folder on your own computer.
