I don't think this is possible right now but please let me know if it is.
Right now it seems like you can do things like:
Kana -> Meaning with just kana displayed. Kana -> Meaning with 'Always show kanji for Hiragana → Meaning questions' enabled, which shows unknown kanji with furigana.
But it doesn't seem like there's a way to quiz kana -> meaning while always seeing furigana for all kanji.
I'd like to try quizzing like this because I think it's usually easier for me to get accustomed to a word through the kana/sound, but at the same time having the kanji be present to reinforce the association seems much better than not seeing it at all.
The idea would be to have my "real" schedule with kanji -> meaning alongside kana -> meaning (as kanji+furigana) schedule generally receiving words first to take on a larger number of words without immediately having to deal with their readings.
I'll be honest - I cannot recall all the different ways this affects it, but have you tried the furigana setting under the Experimental section of Settings? It may not affect this at all, but it might help.
I took a look at the experimental setting, but it doesn't seem to do what I want.
This is the kana > meaning vector, but I'd like it to show that kana as furigana.
Alternatives:
1) Setting a specific schedule to always show furigana for kanji > x even if you know the kanji. 2) Always show kanji hint toggle (not as good as the other options, since it doesn't put the kanji right there in the text).
I am not sure if such a setting should affect kana > x or kanji > x, and I could see arguments for both. The important thing to me is the ability to quiz in a way that is similar to reading text with furigana (exposure to the kanji, but being tested on the kana recognition).
