A new tab on the champion page?

Well, i was thinking of making a new tab on the champion page of the profil where they're only champ you already got a chest on, because the border around the icon is ok, but you don't see the border when you pass fast on all champ, so the new tab can make it more easy to see which champ you're gonna play if you wanna get a chest.

What do you think about that?
