LP gains/losses in match history

I sometimes forget how much LP I earned from a previous game and I think it would be simple enough to add a (+/-)x LP by the (+/-)x IP amounts in the match history inside the client where XP is originally.

It would also make sense to have it replace the XP because to play ranked you already are level 30 and XP is not earned.

We could view it on the official site page for match history but even in-client adds more clarity as to how much progress it takes to get to your next promotion.
