Automatic Unfriend Feature

Not sure if this is the right section to be putting this post but I thought it would be a good idea if we could have an "Automatic Unfriend" option which would automatically unfriend people who haven't played league in (2 weeks, 1 month, etc.) whatever choice you select. It's not something too bothersome but it's a nice quality of life addition to the friend's list. It's very easy to unfriend 1 person to make room for the person you want to add but I think this would make it easier than having to check down the list of everyone's match history.
