The new Notifier→Observer relation chain: * Conversation → ConversationItem, ConversationView * User → UserListItem, UserInfoWindow, UserPopUp * Contact → RosterItem These line up pretty intuitively― if something changes in the conversation, you want the list item and view to change too. But there's one more here that's less intuitive: * User → Conversation If Conversation observes something from a user (i.e., status change), it immediately knows to do one thing only: invalidate the user list, because something's changed.
