Any plans to support user added kanji/vocab?

I want to learn Kanji. WaniKani can easily add 10 more levels to cover for all Joyo Kanji. (I don’t care about N1 anymore, tbh.) Custom levels could an idea, but I don’t know how.

In the process of learning Kanji the WaniKani way, a reading emphasis has to be chosen. Either Kun, On, or Nanori, and which of Kun readings, for instance, has to be learned first. I can’t think of any easy way to do this, other than a spreadsheet and Anki.

Vocab for the sake of remembering Kanji readings have to be added.

For extra vocab, you can always try Houhou. Too bad, I am not on Windows.

In my opinion, however, better learn more vocab in contexts/scenarios/textbook chapters; but for Kanji, it is better to be learned separately.
