Pardon me if someone already suggested something like that and I didn't know of it, because I couldn't find when I searched for it. : I think there can be a feature where people in a room for Multiplayer can see their common beatmaps, so for a quick game they don't have to download new beatmaps but can use their existing ones (and don't need to get kicked out just because of [no map]). And I noticed that profiles for osu do not include showing their friends, so maybe it'll be good if they do, but that's not the main feature I'm more concerned about, though. XD
