@shaggygi we did use the MVVM pattern in the application.  As for the transitions we have our own view stack implementation which is similar in concept to the TransitioningContentControl in the toolkit, it allows us to attach a storyboard to the in and out states as the controls are being swapped out.  The exception to this is the slide back and out, to achieve this we developed a custom control which utilizes storyboards , masking, and a viewbox.

 

@ivan_  you do have to play with storyboards and effects and animations to get the right mix or feel and performance

 

@tropics when designing an oob chrome its an art of making the edges and centers feel just right, and bleed properly.  Glad you like it.

 

Thanks guys
