I installed this userscript so that I could get the hang of which was which (on’yomi and kun’yomi readings), and now I’m much much better at knowing/guessing
I don’t actively memorise “this one is on’yomi! don’t forget!!” or anything, but it is helpful to see the info even briefly during kanji lessons+reviews, and over time get more of a sense of which sounds tend to be on’yomi and which are kun’yomi, and then see how those fit into the vocab.
