Try Go Launcher EX. It has a 5 app dock and can scroll left and right if you want even more than 5.
You'll have to add them to Go Launcher manually. They are still set up correctly on your stock launcher though. Download Home Switcher and you can switch back and forth.all my shortcuts and widgets are gone once I installed the Go Launcher. Is there an easy way to restore my original icons on the home screen from within Go Launcher?
