2 things about Hextech Crafting

#1 So I understand that you can only get a chest on a specific champion 1 time per season with an S rating. What about when you team up with someone else and they get an S rating? I ask because I was playing Ashe, got an A+, but got a chest because a friend reached S rating. All is good. When I go to my champions, however, it shows that I have a chest already for Ashe even though I didn't get an S on Ashe. So does that mean that if I do get an S on Ashe once I have another chest available next week, that I won't be able to unlock a second chest while playing her just because a teammate got an S while I was playing Ashe?

#2 You should make a tab that shows all the things you've currently unlocked with hextech crafting. No functionality to this, just would be nice to see the collection.
