I use it.  What does it do exactly?    I missed the memo, so I only use it for kanji I REALLY know.

I'm happy with Yes/No otherwise-- I don't know I'd want two levels of failure!

I'm going through a huge stack of expired cards in my last stack and have been using a mixture of all 4 of "easy", "yes", as well as the "failed" and "no" you describe. I had a long hiatus and just need to review those stories and links I've forgotten, so I rarely need to revise any of these stories and if I do, I just do it while going through expired cards. Anyway, I've been failing ~80% of these simply cause they're extremely overdue, but once I see the story I remember. Once I've finished a review session I run a script to send all of my red cards to stack 2 since I don't need to waste time studying them. Once I review them when they've failed in stack 2, I pass a lot of them as "easy" because I've actually reviewed them a dozen times in the past and feel very comfortable upon a single review.

So my vote would be for all 4 buttons but others may disagree with added complexity.

I use the "Yes" button for two reasons:
1-When I very easily remember kanji in my forth stack, and feel like I dont need to see it for some time.
2-When I review and sometime just miss a kanji, for some trivial reason. You know, miss read the keyword or something. At that point I will usually fail it just to be sure, but I dont think I need the kanji to start over from the very beginning, so I use easy next time I review it.

I use Easy a lot, I think.  If I get the kanji exactly right, I might get it without a pause, but sometimes I have to actually ponder the story to recall exactly the primitives and the order they should appear.  So, "Easy" and "Yeah, but..."  There could be a "no, but..." I was so close to getting the kanji right.  Maybe I wrote ray for radiance, or envious for envy or healing for heal or something like that.  I know both the kanjis, but I just got a little mixed up.  And then there's NO/FAILED....can't recall the story, or not well enough to guess the kanji correctly, not really even close.

So, I do use Easy and Yes and No all the time.  I'm trying to get the right frequency on the review, so that my study time is most efficient.

Not sure how to name the "failed" stack so that it reduces the stigma.

　What about "Restart" or "Reset"?
or maybe "残念！"? lol

i use "easy" for kanjis that are, well, easy. if i know it so well that it seems like a joke to have to review it, then i click easy.

I think that a three way option of "yes "  "no and "failed" would be great. The "no" option meaning that it doesn't enter the failed box but goes into the second box for review in a few days, as Fabrice first suggested.
The reason for this is because sometimes i'm very close to getting a kanji right but i'm not quite there. I then click on it and see the answer. Staright away the picture is clear and I can write it down and strengthen the image in my mind.  I then click on the failed option and it goes into the failed box. I'm a bit pressed for time so I don't have time to go over all the kanji in the review summary and then the kanji that I almost got is left in the failed box. A few hours later, I return to the failed list to have a look for that kanji but i've completely forgotten which one it is.  The kanji in question then just stays in the failed box and doesn't get moved along like it should do.

I myself never use the "easy" option. I find that ones that first appeared easy are neglected in your mind. You think that because it has only two primitives that it must be easy. But when it comes down to it, it's not that easy at all and is easily forgotten. Also, even kanji that are easy should be written down often to get practice for writing with clear and attracive balance.

I don't bother with the easy button, mainly because I use the keyboard when reviewing and it's a lot of space - y - space - y - space - y ... not really looking at the buttons on the screen. Those kanji that are particularly easy are usually in a high number stack so they're not encounted often anyway.

That new button scheme sounds like a good idea. I think there's a lot of merit in keeping most flashcards in the flow of things, and retiring only the flashcards that are truly bothersome for proper review.

Though this adds another level of complexity to people's answers so it might be wise to have a description of each button's function when it comes time to grade the answer.

As for the button labels, how about: "Yes, kinda, no" ?

I prefer the current system of no/yes/easy. But I admit I don't use the easy option enough, I try to use it more but I feel overconfident when I click it. But I think I'd use the new "No" even less. I usually clear my failed stack everyday, it's the first thing that I do actually, on occasion I'll leave one or two kanji that I still have problems with but that's on purpose.

Thanks. I'm not sure what to do yet, it's not a show stopper though, won't stop anybody from reviewing in the Trinity beta.

adrianbarrit Hmmm, well the intervals could get too long. Looking at the database statistics it appeared that the overall pass rate for all users decreased after 6 successive positive reviews and up. I guess you can't push reviews back forever, especially for characters you don't see enough in your Japanese material. It could be also that you still have plenty of cards that didn't get to box 8 (6-9 months interval), and the current Lietner display on the site obscures the fact that there are 3 more stacks.

For what its worth, about a fifth of my RTK1 cards are in box 8. And I'd like to think that I would remember a lot of those cards after an interval longer than 9 months. It's certainly not a big issue for me, but I think it would be nice if the site could continue to automatically reduce the workload for those cards which I do recall many times in a row.

But I'll shut up now. Because the more of this you read, the longer it will take you to get the superb looking Trinity online! :-)

Sounds good. This is similar to something I was considering where a "No" would first return the card to stack 2, and a "No" on stack 2 (one positive review) would move it to the red stack. This variation has the advantage that a "failed/restudy" option is not needed, so grading the answer is easier, less thinking to do. At most you'd say "no" twice and it would go to the red stack.

Your suggestion could be better to reduce the load of reviews.. If you say "no" on a card in stack 4, say, and you still don't remember it, next time it'll drop to stack 3, then perhaps go back up or eventually, go back to the red stack.
