Provide three lists: "Cards I have seen", "Cards I have learned" and "Cards I am learning"
New cards that I have worked with will automatically be added to "Cards I have seen" and "Cards I am learning".
"Cards I have seen" can not be modified, but from this Master List I can copy a card to "Cards I have learned" or back to "Cards I am learning".
That way I have access to fresh cards ("Cards I am learning") in hands free mode without interruptions of cards I already know very well ("Cards I have learned").
That would work by directly setting the card to one of these options when clicking the green button directly on a card in "Cards I have seen" repeatedly (without opening the card first):
1. "Cards I have learned"
2. "I don't want to learn this card"
3. "Cards I am learning"
This is much faster and more organized than the current setup.
