The Layout Panel is where a project’s mobile app user interface is displayed and designed. By placing elements into Designer View, a corresponding visual element is created in the Layout Panel. For instance, dragging a button element into Designer View will also cause a button to appear in the Layout Panel. This button may then be customized or renamed to match the application's needs. Additionally, users can use and create different layouts to cater to different mobile devices, so an application being run on an iPhone 4S may have a different layout than on an iPad.
