Let me battle from my friends list

Battling random people is very simple, and with a billion-trillion players, you never need to wait for a match. But battling someone specific is currently a more convoluted affair. You need to create a password, and then that other person needs to enter the same password, then you have the game search for others using that word to pair up. It works, and that’s all fine, but it could be so much simpler. There’s a friends list! You can click on profiles of people you’ve befriended, view their battle record, see their emblems, number of cards, and unlocked achievements. But you cannot just click to send a battle request. Which is bonkers.
So, you know, add that.
