It is surprisingly helpful to listen to words/phrases during the learning process, and I wish that would be an option in kanji schedules. As I get that there are several readings and all, nonetheless a random order audio would be absolutely lovely
Thanks for the report! This is not planned, as audio for individual readings are not quite as helpful as one might think. Japanese uses pitch/accents, and that means the way you speak depends on the word. So, a particular reading for a particular kanji does not have a single "correct" pronunciation - it can change depending on the word it appears in.
Because of that, we focus on getting more word audio available which, naturally, is said with the correct pitch :)
