Love this, thank you so much.

After a couple of days of using it, Iāve decided that I love it.
Like some others here, I cherish the S in SRS and place a value on it. But at the same time, I have some seriously evasive leeches and this feature adds a bit of hope for me on that last point 
For now, Iām doing extra study right after my lessons/reviews to see what I would get wrong twice in one sitting --yikesā, or when the review timing is off (e.i. review it in two hoursā¦ but itās midnight and I need to sleep, so letās look at recently learned)!

I have to say I use this feature even more than I thought I would. While I appreciate the long term SRS intervals as they are I found myself making good use of getting a lot more repetitions within the first day of doing lessons - especially for kanji items 
Never engaged much in leech training as I just let the SRS sort it out but maybe now Iāll use this feature for that as well.

Prior to this being released, Iād been using the self-study quiz userscript every day for āextraā study.
Specifically, I used the Ganbarometer to launch self-study for items in apprentice stages 1 and 2, this is roughly equivalent to āRecent Lessonsā for me.
Having now used Extra Study Mode for a few days, the main thing I miss is the ability to āre-quizā only the items I answered incorrectly. (On the other hand, Extra Study also makes it trivial to quiz myself on recent mistakes, something Iād not been doing but now value).
Immediately after leveling up, I often have a fairly large number of āRecent Lessonsā. A majority of these often seem easy because they are familiar or easy to recognize vocabulary from the prior level. Inevitably, though, a smaller fraction are difficult and need more iterations.
With the self-study userscript, Iād developed the habit of going through one round, almost always missing at least a few items, sometimes many. Iād then āre-quizā on just the items I missed, sometimes multiple times if I still made mistakes. Finally, Iād restart the quiz entirely (hitting the enter key instead of the āre-quizā icon on the summary screen). Iād repeat this process until I could get through all items without missing any.
Re-quizzing with just the items I answered incorrectly was a huge time-saver. Right now, for example, I have 46 items in stages 1 and 2 after doing just five lessons. If I were to quiz myself tomorrow morning, Iād probably miss two or three of the five new vocabulary items I just lessoned today. Iād probably also miss two to six or so of the vocabulary items. Re-quizzing just those six or eight items during the middle rounds is much faster than going through all 46 items each time.
Often, the ones I miss are conceptually similar and easy to confuse items that WK seems to intentionally introduce at the same time (e.g. ę °č¬ā¢ę °åā¢ę °å® consolation/condolences/solace ā donāt get me wrong, Iām glad these are introduced at the same time!).
Anyway, the lack of this āre-quiz missed itemsā feature is enough to keep me using the self-study userscript for āRecent Lessonsā (really stage1-2 items).
Iām undecided whether to use extra study mode for āRecent Mistakesā or whether to configure the self-study userscript for items I failed on the last review. Iād also appreciate the ability to re-quiz just the missed items during a āRecent Mistakesā session as well, though.

This is a welcome but long, long overdue additional feature. Itās a step in the right direction, but I think it needs to be more customizable. For example, a practice and review feature just for kanji, just for vocabulary, and just for radicals would be nice. Also, I wish there was a review feature for BURNED items, customizable by level. I would love to go back, when I have time on weekends, etc, and be able to review burned items to ensure that I still know them. I am always worried that as I burn items and will never see them again that I may forget them. Customizable reviews by type (kanji, radical, vocab) and level would be very welcome features. Iād even be willing to pay more for the feature. $9.00 is a very good price for this program; additional features would be worth more, IMO. However, kudos for finally adding a review feature.

This is brilliant. I will certainly use it a lot as I donāt have a scrip.
It would be nice to revisit burned items at some point.
Thank you WK.

I really love this idea of having burned words to review divided into levels and that categories: Kanji level 1, Vocabulary level 1. That would be so great cause as of right now I have WaniKani Kanji 1-5 (in 5 separate decks) and WaniKani Vocabulary 1-5 (also in 5 separate decks) which gives me in Renshuu 10 schedules and it will only get more cluttered overtime. The idea of having them in bite size pieces like this in WaniKani to review for burned ideas would be great.

Thank you so much for this feature! I had taken a couple of months off, and while I came back in January this year, I had quite the back log of over 130 lessons piled up. I was slowly doing one lesson at a time, since I didnāt necessarily remember everything when I came back. With the ability to review newly learned items, I finally got the confidence to just go through my lessons over a few days knowing that I could review them and get more comfortable with the material. This feature has made a world of difference for me in just a few days, just getting rid of my monstrous back log alone has really improved my mentality and revived my excitement. Thanks again.

I love the recent study mistakes until now 
For me it feels especially good that it also doesnāt count on your review level if you get something wrong, so if you did you can just practice again

This is absolutely awesome! I wish it had been there when i started. I am actually considering a resā¦ no, probably not. But this is GREAT! Thank you so much!

Today I noticed what appeared to be a button below my kanji listā¦
Hovering over the little space between the kanji indicated a new native feature. Yeah!!
However the layout appears broken. I use the term broken rather loosely here not to imply blame. Iām sure itās related to a userscript Iām running, although I havenāt started a bisecting removal yet to figure out which one, but intuition tells me itās the legacy review/lesson count rewriting. Yeah, I absolutely hated the space wasting big pictures they moved to a year or so back. Sorry WaniKani, still love you, itās just that screen real estate is a finite resource.
Anyone seeing this as well?

I believe that is caused by my Lessons & Reviews In Header script. Itās already fixed so if you just update it should be fine

I see, it just does the same thing. You can either switch or I think switch out dashboard-progress for extra-study in your script

Thank you for this!!! Iāve gotten so far behind I didnāt think Iād ever catch up (1300+ reviews). Extra study is helping me relearn items that are on the edge of my memory. Iām actually making some progress now, and working through the backlog.

Thank you. Itās great. I like that extra study items come in meaning/pronunciation pairs, which gives sessions a different feel to regular reviews, plus faster.
Hereās another way Iād like extra study to be different from regular reviews: At the end of extra study, if I didnāt get 100%, Iād like the items I got wrong to come back (just the part(s) of the item I got wrong) so I can get them right and close the session at 100%.

A good option in the future would be a function where real leeches could be placed, things that youāve gotten wrong x amount of times and simply wonāt stick, so you can bruteforce them. Because there are some kanji and words that are super rough.
