Runes aftermaths in Match History. What about items aftermaths.

After a game, I often go check what my Runes did. How much HP did I heal off Afterwind? How zapping was my Electrocute? Or how rich did I become off my Kleptomaniac pulsions. It gives more insight and it makes me feel like the new runes have an actual impact. After a bunch of games trying new builds, I realised some items could have the same potential. For instance, how much damage did my Hextech Gunblade active deal, or how often Zhonya's Hourglass saved me from a good beating. Maybe simply see how much I healed off the stats of a lifesteal item, or Redemption. I would really enjoy to see it come to League of Legends one day, and seeing how reliable Runes stats are, I know it can be done by our beloved Rioters.
