It also provides a quick way of seeing how your album will look on various devices, to select a device to emulate click on the 'mobile devices' icon and select a device/size from the dropdown list. You can rotate the 'device' by clicking on the rotate icon, toggling between landscape to portrait orientation.
Just discovered this, nice feature! Is it possible to add to these options? If not, can I request an update to some more modern devices/sizes, please?
