Getting reviews / practising after finishing WaniKani

I’m at a different point in my Japanese learning journey… but you could take a look at the [Userscript] Self-Study Quiz It let’s you review items outside of the wanikani schedule. Like for example you could start to just review some kanji level by level and then if you feel like you need some more practice on some, unburn only those to put them into the regular review schedule again.

I have no experience with this, but it sounds more effective than just unburning everything or so.
