Hey, I Use Anki a lot on Desktop and when I want to add a card I don’t want to have two windows (one is deck window and another is add window) on my display; just one of them that convert to another (deck window converts to add window! and vice versa)
and beside that I think you need to develop an adder assistant for adding flashcard when the users reading books and pamphlets; It may be good to use some AI for card generation (something that works with a shortcut, and is light and easy to use and free as always!)
