I loved the nova launchr. Used it for a couple years. There is an option to import touch wiz home screen, and normally it brings everything over. However when importing it puts all the icons and applications in their proper places that I had on touch wiz home screen, but it does not put the actual app icons, only the filler android bot icon. The green one, in the place of all of the app icons.
I went ahead and used Nova again, because I do want the landscape and other gestures. I just had to redo the home screen icons in Nova, and not import the ones from touch wiz
