I would like to have "away", "busy" and "available" mode options and text displayed beside all avatar names in my friends list. The same way as in MSN, Skype, Yahoo messengers etc. You should not only see their mode by their name above their head if you stand beside the avatars on the very same parcel, but also in the friends list if you happen to be in totally different places in the world. This will also prevent people from starting useless conversations with you if you're not even by the computer of if you really want to be by yourself for the moment.
I would also appreciate to be able to send the same message to all my friends or some of them at the same time by ticking or selecting their names in the friends list. This would be great for party invites and things like that. You might say I should start a friends group, but what if I don't want to have all of my friends in that friends group and don't want them to see that they're not chosen to be in that group by clicking this group in my profile and read through the group list of names. Maybe I don't want to group all of them but still want to be able to send them group messages via the friends list.
