So specific attention is paid to which information is presented on a specific view of the application. Smartphones, paired with tablet-related devices, and the possibility to rotate the screen, impose a specific focus on the "responsiveness" of the application, that is, the ability to adapt content layout, as visibility or rearranging, to different and mutable resolution specification. This specifically means that orientation can change during the same running application, as the device can be rotated during usage. And generally, we cannot develop different versions for any specific resolution, as today we already have many different current resolution specifications...
