Best news this weekend. Can confirm the script works with console. Many thanks.
Console trick doesnât work for me on Firefox. Nothing happens at all.
Are there errors in the console or just nothing happens?
Alright, as far as I can tell I got it working now. You can get the new unofficial console-only version here. Please let me know if you run into any issues. At this point Iâll be pivoting to the UI to try to get that working again, and once that is working I release the update officially to everyone. (Itâs possible that wonât be for a bit since I donât plan to work on this every day.)

Sorry mate, it was pilot error because I misinterpreted what a ânullâ value did. I just tried it again with 1.9.1 and I can confirm it does in fact work. Thanks for getting a fix out so quickly, I can now get back to my normal routine

Looking for more feedback!
As already mentioned, I do have the core functionality of Lesson Filter working again. However, there are some compatibility issues if you use other scripts that change the queue, such as Reorder Omega. In Omegaâs case, this happens just by it being installed, even if you donât have it set to do anything during lessons. Itâs possible that I can integrate with Reorder Omega by using the same library that Omega uses for manipulating the lesson queue, but some Lesson Filter behavior would have to change to accommodate that. So I wanted to poll a few more things to see if thatâs desirable.
First I want to see how important compatibility with other scripts like Reorder Omega is by finding out how many people have a script like that installed or use it.
Do you use another script for lesson filtering or reordering? (e.g. Reorder Omega)
- Yes, during the lesson learning portion (the part Lesson Filter is available in)
- Yes, but only during the lesson quiz portion
- No, but I use one for reviews / self-study / something else thatâs not lesson-related
- No, I do not have a script like this installed

Next I want to know if people use Lesson Filter to make changes after completing at least one batch of lessons.
Do you Filter or Shuffle after having already completed the quiz for at least one lesson batch (without page refresh)?
- Yes, sometimes I filter again after completing a batch
- Yes, sometimes I shuffle again after completing a batch
- No

Related to this, right now if you filter multiple times (in a row or again after the quiz) the filters apply on top of each other. For example, if you first do radicals=0, kanji=5, vocab=20 and then do radicals=3, kanji=7, vocab=12, you actually end up with radicals=0, kanji=5, vocab=12. I want to know if this is desirable behavior or if it would be better to âthrow outâ the first filter and then apply the second filter to the whole/original set of lessons.
How do you want filtering multiple times with different values to work?
- Apply the filters cumulatively (how it works today) as explained above
- Throw away previous filters and apply the new filter to the whole queue
- No preference / I wonât use filter more than once anyway

Adding compatibility with Reorder Omega would require some changes (as alluded to in the above polls), but ultimately I donât know which is more important.
Which of these is more important?
- Lesson Filter and Reorder Omega work together
- Filtering more than once applies cumulatively (option #1 above)
- No preference / I donât care about either of these things

Iâll leave these polls open for the rest of the week and decide what to do this coming weekend.

i use a script to sort reviews by srs level, and one to sort lessons (to give me a mix of kanji and vocab, rather that 30 kanji followed by 120 vocab). as these are really quite different tasks, i reckon they are best left to separate scripts.
I very rarely filter more than once. It might happen if I change my mind at the last minute about the mix of items I want, so it would only happen before a quiz rather than after.
However, if I did filter more than once, I think it would be confusing if the effect of the filters were cumulative, if Iâm understanding this correctly. Seems to me that this is not something users would expect to happen.
If multiple filters are cumulative, the user would need a way to back out of the process, or be stuck with (for example) zero of one category with no way to increase it after the initial filter.

To be clear Iâm not planning to add functionality beyond what Lesson Filter already does. Itâs just that right now Reorder Omega breaks Lesson Filter if itâs enabled on the lesson page.

Right, the fact that no one has complained about this in the past (since this is how it worked before the recent WaniKani update) indicates that itâs probably not common to filter more than once.
Well up until now the âresetâ was to refresh the page. 
But yes I agree with your point on the whole. I was thinking of making a new Reset button to allow this (exposing the method I already added behind the scenes). But just changing Filter to start from scratch would probably achieve the same goal while keeping things simpler.

I occasionally filter more than once if I finish a batch of 5 and then want to do another batch of 5 but I am totally okay with just having to refresh the lesson page and start a new filter from scratch in that case if it would be difficult to code.
EDIT: based on your previous reply about how it used to work, I think I might have been refreshing between most of the time anyway and so never noticed?
Iâm a little confused by the description of the filters applying on top of each other.
If applying filters consecutively, expected behavior from my perspective would be that any new numbers entered would apply to the remaining lesson queue (minus the ones already quizzed).
For example:
radicals: 3, kanji: 1, vocab: 1
for one batch of 5 lessons, take the quiz, then:
radicals: 0, kanji: 2, vocab: 3
for another batch of 5 lessons.

Yeah, perhaps my description wasnât great. With either approach, filtering again after the quiz will obviously exclude the completed/quizzed lessons.
The difference is that currently it will not add back filtered out lessons. Currently, if you filter to zero radicals, complete a lesson quiz consisting of kanji and vocab, then decide you do want some radicals, you canât filter again to add the radicals back. Youâd have to refresh the page.
If I switch to use this shared library that Reorder Omega already uses, this would no longer be the case. In this case any filter would apply to the unfiltered queue (completed/quizzed lessons excluded of course). So using the example above, you could add back in radicals after the quiz without refreshing the page. (I can easily change Lesson Filter to work this way even without using that library. Itâs just that with the library I have no choice.)

Any insights? I thought I ran this correctly, but the page isnât updating.
Wanikani Lesson Filter 1.9.1
Firefox 104.0.2
Console output
Other installed scripts:
I know this image says 1.3.2, but itâs 1.9.1 I set the version to make sure an official update would prompt to overwrite. I am not familiar with how tampermonkey determines how/when to install over things.
Iâm not sure why youâre getting this error, but you donât need to worry about the version thing. I used 1.9.x for the unofficial release because I plan to use 2.0.0 for the official release. So even if you keep 1.9.1 youâll get the official update.

I donât know what causes the error you are seeing but I would turn off all the other scripts and see if thatâs the problem. I am using 1.9.1 on Firefox 111 with the following scripts enabled.

There is one possibility. The script assumes that Turbo is available on page load, but maybe in some weird situations itâs not. If thatâs the case I think I can tweak how I access Turbo to reduce the chance of this happening. I canât guarantee it will fix the issue, but if it doesnât cause any problems Iâll do it just to be safe. Since Iâve already started making the UI changes though itâll probably have to wait for the full release.

Might have missed something, but where do I actually get version 1.9.1?
Thereâs a link a few posts back. Itâs a partial fix until I can get the UI fully working.

Ahhh, interesting. I actually had no idea it did that, but I realize I probably was refreshing the page between each filter application since usually I find I do want to start with something like â2 kanji, 3 vocabâ and then if I feel comfortable with that (or already know some of the kanji or vocab in question from outside WK) after the quiz do another group of â2 kanji, 3 vocabâ or â1 kanji, 4 vocab.â
But again, Iâm definitely fine with having to refresh the page in between or click a ârefreshâ or âresetâ button in order to get that behavior.
I donât know if this supports your hypothesis or not; but pasting the whole script into the console and then calling the window.lessonFilter.filter function works.
The context hider user-script was also not working. When I re-pasted that it snapped to working. So I tried with the lesson filter script.
