Feature request: radicals

[disgustingBot]

First of all I really like KanaDojo, I'm considering becoming a contributor once I'm done with exams and get some free time. Anyways. I like how you can practice independently kana, vocab and Kanji, and I was wondering if maybe something similar could be added to learn the radicals. This really helps for things like looking up words/kanji you don't know.
Thank you so much for creating this app ❤️
