With the iPad app, the same transition calls for tapping a Years button on the navigation bar at the top of the screen, selecting the year as it appears in a popover box and then sorting through that year.
Similarly, commands are hidden off screen and can be drawn up from the bottom or down from the top with a finger swipe. The commands shown depend on what object on the screen is designated. So if a photo is highlighted, the commands might include delete or upload.
In the iPad app, that is done via the always visible navigation bar.
On the iPad app, search is done via a search window on the app's home page. With Metro, it's always available on the charms bar - a bar of a consistent set of icons that can be swiped out from the right hand side of the screen. It searches the application that the user is inside of.
The features go on and on, including sharing content between applications and to various social networking sites.
