Description of your request or bug report: It seems a bit silly to have to toggle furigana for each individual book provider, especially if there are 15 of them:
I would think it would only be special cases where a version of a book is sold with (or without furigana) at specific providers only. In that case, could a button be added that toggles all the furigana notations at once? Or move the furigana notation from the book provider list to somewhere else? Maybe in the “general info” section?
