At the top 40 scoreboard of a map, if one (or more) of your friends got a place there, that score it's marked/coloured with orange, and ingame, at the top 40 score tab at the left when the player is playing map, that score is coloured/marked with pink to let you know that one of your friends got a place there.. and.. when you click "Settings" in the osu! page, it shows you which friends are online right now, browsing the page.GigaClon wrote:
What is the purpose of friendship anyway, the only thing it seems to do is tell me when people are online
But anyway, you're right, friendship isn't useful at all, and neither is this feature. I don't support this.
