challanges, achievements, icons, backgrounds...

There are these hidden icons you can get example: buy skin during harrowing or gift friend. etc. So I've been thinking if there would be "Achievements" tab on summoners profile. there could be some achievements like get penta, get 3 quadra kills, play 50 ARAM matches, win 20 Team Builder games etc. While doing those challenges summoner could get new icons or maybe background arts on his/her profile as an reward for low lvl players possibly ip/xp boosts.
