Mock-ups for Notifications in Windows 8.1

i just again wonderd why only skype is using some sort of advanced notifications in windows 8.1. What Features would you like to see in the Notifications? Quick Flag/Response a Mail? (therefore, i think, the notification would have to stay open)

Or do we dont need this at all?
