Make your own flash cards
I would really love the ability to turn off auto generated flashcards and tell readlang when I want a flashcard made. Because it auto generates them, I find that it creates way too many flashcards and it's impossible for me to review them all. This means I have to go through and delete many of the auto generated flashcards, which is tedious and ineffective.
Please check out this mode allowing you to delete flashcards very easily while reading which isn't exactly what you're asking for but may help: https://blog.readlang.com/2023/06/09/delete-on-untranslate.html
