Amount of LP Earned shown in different places than Winning Screen I.E. Match History

Hi. I wanted that Riot bring a feature that it shows how much LP you earn in Match History rather than remembering it from winning a match. I disconnected one match and wasn't able to figure out how much LP i gain. It wouldn't be something big but it would make sense to put it on the match history. What are your thoughts on this? Are there similar discussions like this? (List Link). Thanks.
