The old rememorize add-on didn’t show when a card was rescheduled in the card’s history, and I think that is nicer than the current way of saying “manual” in a card’s history (accessed when you go to a card’s info). Some people get behind for long periods of time and have to continually set due dates for cards, and this would clutter the history of many cards (potentially). If there could be an option to show the manual tag that might be best, or remove it altogether because knowing one rescheduled it isn’t as important as knowing when one last correctly guessed, missed, etc. a card.
