Ahhhhhh gotcha! Honestly itād be pretty hard to implement because using ęč§ as an example, iirc you learn that pretty early on with WK. Considering thatās a late N3 point here it would probably just lead to more trouble than itās worth unfortunately. Iām not sure if the grammar points now on BP default to Kanji when search under All - if they do, you could just scroll down and see if one catches your eye that youāve learned I guess? Only other way would be to export the WK vocab list into excel and do the same for BP and see what similarities arise.
Not worth the effort imo ^^ Maybe someone has a better suggestion that me. Thereās bound to be a thread somewhere on the WK forum where someone has asked which vocab words corresponds to any purely JLPT grammar point, but that doesnāt really answer your problem. Maybe someone fancy with coding could create something that has the database of every WK vocab word and when you open the All page on BP itād highlight said vocab words.
