In the past I've done alot of ROM theming and eventually moved into creating LauncherPro themes to go along with the overall theme of the phone. I'll be posting those LauncherPro themes here in this thread. So far I've been mimicking Stock UI's and have created skins for Droid X/2 and Galaxy phones. These themed LP's do not require you to be rooted. Just simply install each .apk with a file manger as you would any other app. You must uninstall LauncherPro if you have the market version already on your phone. You WON'T be able to get market updates for this app if you install my version (unless you uninstall again). I've also include equivalent icons and dock backgrounds for each theme.
Galaxy S Theme
Version 1: GalaS-LauncherPro-0.8.1.1.apk (Transparent widget backgrounds)
Version 2: GalaS2-LauncherPro-0.8.1.1.apk (Grey widget backgrounds)
