Pick a card should show card picks if there are cards to be picked (as it is now) or cards that are dismissed, so that you can add them again from there instead of the "Start Learning" button. For now, I need to create a dummy card (if all cards have been committed to a state) in order to access this screen.

We should be able to swap cards left or right from the pick a card menu to send that card to the back of the pile. Sometimes you want to scroll through only. Whether you are just not ready to add a specific card, or that you are trying to find a specific dismissed card. Those would be more helpful than to go through the whole list in the pack.

Possibility for a card to be put back into the middle pile / neutral status (Not "To learn" or "Dismissed"). If you want to put them back there, it is impossible. If you have committed a card already, you are stuck with a state and cannot put it back into the middle pile.

Piggybacking on the last one, removing a card from the learning list should not automatically dismiss a card. You could ask the user if they want it dismissed or not, and if not, put it back in the pack pile as a neutral card.
