Note as well that a panorama adds more memory usage to your app and will make it harder to let an app start up fast. In my case I designed the app in such a way that the app starts with the panorama almost empty except for menu/welcome screen and the other panorama items (view/viewcontrols) are added dynamically after the loaded event of the main page or even later, since the items at the right of the panorama the user will not see immediately at start up.
