Give us more Options to Sort our Friends List

So right now I've got the problem that I've hit the max friend limit (324 apparently). The main reason is issue it's reeeeeeeeaaaaalllllllyyy tedious right now to go through my list sorting out everyone I don't know/never play with with the people I kinda know and play with on occasion.

So why not just let us sort who we've played with recently, or accounts that have been inactive for a long time so we can remove them in bulk without having to do it one at a time for what feels like a whole day?
