Surprised to find that for new cards while I treat the easy button as “I’ve mastered it.”, lots of people would go “It’s easy to learn.”
The difference here is that the knowledge has rooted in mind for the former case, while is new but easy to assimilate for the latter.
It would be a waste of time to push the easy button for the mastered card since there is no need to see it again, unless the user has put so much time in the same deck/preset that anki has captured the very unique button push pattern.
Maybe it would be better to just flag and suspend the mastered one.
