There are some things about the interface that I really like. Two tings in particular I would like to not lose are: Swipe to left or right at top to change brightness Swipe down from the top, from any screen, to pull down the settings for Wi-Fi, Blue Tooth, etc. I suspect the answer would be same for both. Will that functionality be lost if I install Launcher Pro? (I'm not sure what is part of TouchWiz, and what is not).
