Get nova even if you don't want it now! I landscape home screen mode!!
Everybody needs nova launcher. It doesn't have a huge effect on battery life, great customisation with custom grids and all. It's perfect and looks much better that touch wiz with the standard jelly bean icons.
It's so worth the effort and it has the option to just copy the arrangement of the layout you have on touch wiz.
Most importantly though it has an auto rotate mode! So there's a landscape mode on the home screen! Makes a huge difference! I
Glad I stumbled across it. And I thought touch wiz didn't suck like everybody said! I :P
