Apparently the KDE network icon is white when connected and has a splash of green on it when disconnected. Green? I'm not quite sure because I think I've seen a splash of red on it sometimes. I know...just google it. But why can't it just be obvious? I usually have to waste time by hovering my mouse over it to find out. How about green for connected and red for disconnected? You know...like traffic lights. The gnome network icon shows a connected line when...you guessed it...connected. And broke line when...disconnected. I've never had to google the gnome network icon to understand what it means...Obvious!
