Because I am thinking that maybe at this step:
People are also wanting to test themselves on the reading of the target word – can I understand the sentence and read the kanji 丸?→ then decide Hard or Good.
They also might just want their current furigana settings to also affect this location.
But yeah, Reading + Fill-in-the-blank mode is super new, and this is the first time I’ve seen this requested. I don’t wanna break other people’s study system with a change like this, hence suggesting the optional hotkey (which is a non-breaking change).
If you or anyone else has more opinions on this, would love to hear them!
