Afk Reminder/ notification for league app

I have an Idea for a notification for the league friends app that one tells you when your friends are finished with a game, and two a feature that notifies if u go afk to go to the restroom or grab something to drink. This notification would then prompt you if you want to continue playing and if you said yes your afk status would be reset and you would have say 2 mins again to return to the game if you said no you would leave for afk and be penalized like normal. To make this idea far less exploitable a player should only be able to use the afk reset once per game, I feel that this Idea could be quite helpful for many players who feel that they are unjustly penalized for going afk for involuntary things that are excusable, however I don't feel that those who leave their computer in game and go run an errand should go penalized.
