Should have option to enable landscape mode(view) for home screen same as google launcher. which will enable to enhance to user experience.
Having option to enabling landscape mode(view) for rotated home screen from vertical to horizontal (landscape) view same as tablet.
somewhat like desktop view.
if user used any application in landscape mode and get back to home screen for to switch application he need to rotated device from landscape to vertically.
so to avoid this if launcher having this option it will enable user to use phone even on landscape mode without rotating actual device.
