Soon after getting osu supporter I learned how fun it is to view the friend ranking section of beat-maps. Getting to compare scores is great already, and trying to beat other friends scores and getting to challenge them to beat your own plays back is super fun. Given this, I think it would be cool if there was a dedicated screen where you could view friends recent top plays, and be informed of when they beat one of your own plays. This could be updated in real time and would eliminate the process of happening to stumble upon a beat map with a friends ranking on it. If this could become some sort of pseudo friendly competitive network I think it would greatly add to player enjoyment. Hell, its already entertaining to watch osu streamers who are friends try to snipe each others plays.
