I have OS X 10.8, and one thing I don't understand about the new Notifications system is that the icon in the menu bar doesn't tell me whether I have any notifications or not. The icon ( ) looks the same to me whether I have notifications or not. Every once in a while I'll click on it, and realize that I have Notifications from weeks earlier.
Am I missing how this is supposed to be used? Is there a way to have this icon change color when there are notifications? Can I simply disable this panel and icon?
