This is an epic post – thanks for taking the time to make it @jordanne! This is so inspiring 
Much of this resonates with me. Thanks for sharing many of your personal spaces, even at potato-quality (that’s a new phrase to me 
). I have lots of personal spaces too that I want to share, but at the same time I don’t want to share everything because they are a bit revealing too. (That’s why sometimes I anonymize my card names before sharing a screenshot. I think that speaks to how flexible and expressive Kinopio is.
Your instinct to embed Kinopio into Notion is discerning. I think this area of interoperability with other systems is fertile. Imagine if you could make a card in Kinopio that syncs with a block in Notion. Oftentimes when I’m using Kinopio, I want to be able to view my data in a more structured manner: as a list, in a table, with more rigid hierarchy. What makes Kinopio great is its flexibility, so maybe this other view is not built-in (although it could be), but what if it syncs with another tool. Thanks to the API that @pirijan has provided, the pieces are basically there to do something like this.
Congratulations!
