It would be so nice if the notification center shows you the 'today' view when you have no notifications. Same with the Lockscreen. The clock and date is on the upper right of the screen in this view, so nobody would think his widgets are actual notifications (lockscreen). Or if you could swipe down in the right side statusbar to reveal the notification view and swipe on the left side to bring up the today view. I could imagine a seperate settings section in the settings app for that.
