Samsung Galaxy S Program Launcher for HTC Desire
The Samsung Galaxy S runs a custom program launcher by Samsung, which adds some extra functionality to the standard Android launcher. You can place 4 icons on the bottom of the home screen.
The icon on the right is the Applications icon. Pushing this button will show up the actual program launcher. You can scroll through the various programs by swiping left or right, just as you would do when you use the Android home interface.
Now, this launcher has been ported to the HTC Desire. XDA member inkredi reports about the mod, which should work on Froyo builds FRF72 and FRF83:
