FSRS toggle should not be global It makes sense for FSRS to be the default for new profiles, but it makes no sense that the FSRS/ Legacy SM-2 toggle is one for all profiles. Some users (like me) have needs for the old algorithm in specific decks, so I need to use SM-2 for them. Basically, due to h…

You probably mean “presets” sincre different “profiles” can have different algorithms, I think [1] . You can edit the optimization filter in the deck options to allow suspended cards to be part of the optimization. You say that that would “makes the intervals shorter than they should be”, but if that…

That would be very nice! FSRS is great, but SM-2 still has its place. It would be awesome to be able to use FSRS for most decks but SM-2 for special decks where SM-2 behaviors were preferable.

The FSRS contributors are seeking sponsors on GitHub so I expect that with increased support from the community they may eventually be able to add such advanced features. (but I’m not involved with them so I don’t know if that’s possible or not.) github: fsrs4anki github sponsor (Asuka Minato)

yeah, presets. Thanks for the info regarding fsrs options. As you well noted it’s not certain that considering those cards makes the algo innefective. In theory shouldn’t pose a problem I guess

Would it do any harm to keep changing the setting back and forth depending on which deck you are practicing? Obviously it wouldn’t be as convenient, and being able to set it per-deck would be preferable. But if that feature just isn’t going to happen, then for some use cases switching the setting b…

Also, here’s a crude little Anki addon I just wrote for myself to help with the switching back and forth thing. I’m planning to switch back and forth because my first experiences with FSRS didn’t go well, but I don’t want to give up on it. So I’m going to keep using SM-2 for most cards for now, but…

One alternative to FSRS is a project called Anki SRS Kai, it is based on SM2 and incorporates features from SM2 add-ons, so its performance is probably about midway between FSRS and SM2. But it’s developed by an individual and isn’t actively maintained, so I think it doesn’t have FSRS like community…
