Why isn there a quiz mode or revision export for Kana?
As for most other “why isn’t there an option to do [xxx]?”, the short answer is that I haven’t got around to implement it yet and that, maybe one day, when I have time. The longer and slightly more realistic answer is that, given the amount of free time I have (precious little) and the amount of potential features that outrank kana options (heaps and heaps), you are unlikely to see much new kana features until a very hypothetical Kanji Box Inc. IPO on the NASDAQ allows me to quit my dayjob. Kana are only a secondary feature of Kanji Box, as they are [comparatively] rather easy to learn and shouldn’t take a devoted student more than a couple weeks (whereas you can easily spend years on the kanji/vocab/reading parts: trust me on this). Of course, if you beg to differ with these priorities, and so does your wallet, please by all mean make me an offer I can’t refuse.
