It would be great if the details of the animation weren't tied to the theme. For example, if you want the "parading dots" motif, you have to go with Windows8, Windows8Touch, or one of the "2013" themes. 

The control should have an "AnimationStyle" enumeration property, where you can select which animation you want, independent of the theme. Even better, it would be great if you could specify your own animation.

Thanks!
