Rotate the wallpaper on the lock screen
Have an option that one can select that will rotate the wallpaper (in order or at random) on the lock screen. It could use a "Wallpapers" folder in the Picture hub. One can set it to change the wallpaper after every time the phone locks, or a certain number of locks, or a selected about of time, etc. Just to add some customizable variety (I like the Bing option, but I'm not the one selecting the images) to the lock screen image, and so I don't have to change it manually.
YES... will be great...
