Based on this documentation for orbit, I think it would be possible to write a plugin that would allow turning notes into mnemonic medium. I’m mulling over in my head what the best UX would be.
Here’s how I imagine it COULD work. Users could take their notes and embed prompts / questions for themselves into the notes, and then use Orbit to review. However, I’m not sure it would have any value. I do like the idea of a spaced repetition system with a nicer UI than Anki. But, Anki is a proven thing, and Orbit is much more of an experimental playground.
