Review navigation is currently optimized for keyboard use, with the spacebar and arrow keys. There are also on-screen buttons, but they’re far down the screen, so moving the cursor to click them takes extra effort. Would it be possible to add touchpad gestures? Ideally, tapping a card would emulate the spacebar, a two-finger tap would mark it as “forgot,” and swiping left or right would navigate to the previous or next card.
