Good read! I ran into points 3) "learning out of context" and 6) "missing the big picture" regularly myself when studying with Anki. I created a spaced repetition app [1] which lets you link and nest flashcards (like notes in roam research) to address this. The name of your method suggest it's tied closely to Anki, but from what I read it would work even better with connected notes?
