I have two options in mind: either a button to copy the sentence/word, or a button to toggle the furigana. Sometimes I copy things out into other services, examples include jisho.org, text-to-speech, and ChatGPT. Each time I do so, I need to clean out the furigana which gets copied as hiragana going after the kanji.
I do not have time at the moment to consider this, but it is something I can consider for the future! I have a few other things I want to add to the sentence "interface", so I'm doing what I can to keep it from getting too packed with buttons and options.
