Re: i have had the S4 from launch what home launcher
Other than, as DenverRalphy says, TW specific widgets, there is no real downside to another launcher. There are plusses - my main reason for using a launcher (Apex in my case - fast and simple) is just to get more icons on the home screen. The stupid, unchangeable 4x4 basic Android grid is a real waste of space and you'd think that limitation would be long gone by now.
