Tap to turn. The app is for ipad, it’s unintuitive then that the flash card starts on typing and you have to tap into a different screen to start writing with stylus. Generally, no one using goodnotes is trying to type their things. I also don’t like having to go in and out in and out to write the question and then it’s answer, I suggest having a double tap feature where the card in question is able to flip for ease of editing either sides.
