In Roam and Anki, it’s possible to make spaced repetition items for content that wouldn’t generate cards in RemNote’s current implementation. So I think it would be useful to add an option for spaced repetition to plain Rems in RemNote.
This would be useful for e.g. tasks that do not explicitly require content recall but can still be graded using spaced repetition e.g. “practice this section of this piece on the piano”, “practice this dance movement/martial arts form/etc.”
