Feature request: Ability to see a damage report on an opponent I have recently killed

If someone kills me I look at the death report and see whether it's AD or AP and if there's anything specific that I can itemize against. The enemy can do the same if I kill him. But I can't ever see what my damage output looks like. A lane opponent has more information about how I deal damage than I do! Example: in a recent game I played Shen , Eye of Twilight . In the after-game report I can see that I did twice as much magic damage as AD. Probably most of that was from my Sunfire Cape while standing in a pile of minions though. Against champions the magic damage from my enhanced basic attacks after Q was probably more prominent. However I have no way of knowing. Request: Make an icon appear for 10 seconds after killing an opponent that can be clicked on to show what damage you killed them with.

-Thanks

PS: Added benefit, you can now prove whether it was a KS!
