I have just added memorable names to all image radicals.
Actually, I create a Git repo for this (but on my private Git website, as I am not sure that I will touch too many licensed WaniKani contents). Private also means that I might not keep the website running forever.
Note that, the exact same way can also be done in this forum (WaniKani Community / Discourse), by creating replies for every radicals and non-Wanikani kanji; though it will be harder to both make a Wiki and spoiler.
Making the first post (OP) a Wiki is an easiest way in this case. As I find more contents, I will share.
