I think it would be nice to be able to see what radicals/kanji/vocab are at a certain stage (apprentice, guru, master, enlightened, burned) instead of just seeing the numbers by hovering over them. We would be able to click into one of the five stages to see a page interface for all the items at that stage, split into the usual categories of radical, kanji and vocabulary.
I feel like this kind of thing has probably already been mentioned elsewhere, but I couldn’t find it. Sorry if this is a duplicate!
WKstats has such a function. The URL should be wkstats , but I’m getting 404’d at the moment…
Edit: Well yeah, I guess that works too. https://www.wkstats.com:10001/items/wanikani is the specific page you want - click the “Open Config” button if it’s not already open, and that’ll let you show or hide things by type or by SRS level. And other things.
