Hi,
it would be really cool if there was a setting to switch the WK interface to 日本語 (not all the settings, just the common stuff you see daily, menus and the review/lesson UI). An awesome way to achieve this would be to gradually switch the interface to Japanese as the user unlocks the relevant words (for reviews you basically only need 部首, 漢字, 単語, 読み方 and 意味)
Maybe there is already a userscript for this?
Greetings
