Normally when you're browsing the client you hear a bunch of random sounds that are supposed to let you know when someone has said something on the chat room, someone has joined the chatroom, your friend is online, etc.
The problem? i don't know what's going on. There's really no way to tell what just happened. Keeping track of that many things hapenning on different windows that most of the times are minimized is really impossible, specially if there's no way to see what just happened. (I would suggest a status window but that would only add up to the problem of having too many windows that you barely have on screen). So most of the times i just feel that my client just farted and i have to akwardly ignore it until it happens again.
I know this was already noted by Jay (thanks for listening on the game chat <3) but i thought it was worth discussing.
