When using sentence questions for vocabulary quizzes, I'd like the quizzed term to always be shown with furigana in the "correct/wrong" confirmation's repetition of the sentence, so it's a bit easier to reinforce the correct pronunciation while doing e.g. kanji->meaning questions. On a phone, the sentence is usually visible without requiring scrolling, while the dictionary entry box is more often bumped off-screen by longer question/answer/repeated-sentence text.
For example, I'd prefer if this included こしょう above 故障した in the sentence (only after answering!), regardless of me knowing the relevant kanji:
Thanks for the suggestion! I cannot say if and when I'll be able to consider this, but I think furigana presence/absence is an area where I've gotten a lot of scattered requests over the years. It's a tricky one - everyone has such wildly differently sized devices, that some of them have too much space for renshuu, while others don't have enough, and I have to keep them all balanced.
