I don’t know if it is in the scope desired by @dae, but I’ll make this suggestion here.
Maximum interval, though not recommended, can be useful on occasion. I’m applying for getting a position, process in which there will be a major test, of enormous scope, and I don’t know when (maybe 2, 3, 5 years from now). I didn’t use maximum interval, but as I started getting intervals as long as 3 - 5 years, about very important contents, sometimes difficult contents and/or easy to forget because of interference of very similar other contents, I feared these intervals be too long, and adjusted a maximum interval of 1.5 years to ensure I will not forget the cards till the date of the test (at the same time, not too short, so as to avoid increasing beyond reason my working load).
But there are some cards that are too easy, or which somehow merely support contents, which where a basis for understanding something else but not part of what will be charged in the test, and as I firmly believe Anki algorithm, I know that for them there would be no problem in using the regular scheduling, bypassing maximum interval.
So, in the same deck, I have a majority of cards to which I would like to avoid extremely long intervals (like 5 years), but also a few cards to which I would prefer the regular scheduling, bypassing the maximum interval.
I looks for me that this is an issue only for me, but that many users may have the same desire.
If you could implement, beyond the 4 regular answer buttons (1, 2, 3 and 4), one or two more, standing for Good and Easy bypassing maximum interval, that is, scheduling the specific card being reviewed without considering the maximum interval set in the deck options, that would be terrific!
Off course, it would not be necessary to show these buttons in the reviewing window; they could be an option inside “More”, or simply have a shortcut attached to these functions.
Thanks anyway!!
