    This would be part of the solution. The other half would be the ability to change grades (or repetition intervals - please!) in the database.

    I guess there is something like the current repetition interval and the multiplier (that makes even cards graded '2' receiving high intervals after a while). Both should be editable.

    But I see this suggestion has been here since 2012. Is it dead? Such a seemingly small change, and so wanted, yet stubbornly unimplemented - is it any use spending votes on it?

    Yes, I just wanted to add this feature. The possibility to give a quick grading to your answer when reviewing cards is important. On the other side, it happens I hit the wrong key. An undo function would be helpful.
    Thanks for anyone attending to this opportunity for improvement.

    I've made over 10,000 cards, and it's hard to express how obnoxious this is. For me, it's needed when making cards (and accidentally hitting the space bar) or reviewing cards and hitting the wrong key. This was brought up in 2008, it's surprising that it hasn't yet been implemented.

    Undo will be great! I think Undo should be not only for last card but for several previews cards too. I think it is most lacking feature in the program.

    Following the example of Firefox's "session.js" file and backups, giving at least the possibility to the user to have 1 (or X) database journal backup corresponding to the state of the actual-1 action (or actual-X actions) would be a very helpful feature yet probably "quick" to implement.

    So basically, this would be "go back" and "skip ahead" buttons that allow you to go back and forward as many cards as you want and grade again if desired.

    Peter, would you please add { on Review Information Bar } the Last graded card Next interval.
    That info would help to decide whether or not to 'Redo' the Last card.
    The reason of "Undo last" is to change the Next interval not the grade per se. Without seeing the Next interval, users will just waste time re-grading Mature cards { interval 1 mo or more } because on Mature cards it will not matter whether you grade it 2 3 or 4 ; the cards will be scheduled a few months in the future. I verified it many times.
    This option will be very useful for the first few repetitions -- when Interval variation makes huge impact on the recall.

    I've made so many mistakes while grading cards and this idea came to my mind! that would be great feature!

  • Fabien Goujon commented  ·   ·  Flag as inappropriate

    It would be very interesting. I regularly click too fast on a wrong grade. Sometimes it comes to my mind one or two card later, beeing able to go several cards back is a good idea.

    I would use this after I have given a card a higher grade than was appropriate -- usually because I answered too quickly.
