In the current version of Go Launcher the dock can be removed in preferences. This is useful when you want widgets in the dock. Even though its not a real dock. I just made by grid have 6 rows and then using editing software put a black bar at the bottom of my wallpaper image. So I put my shortcuts in widget that I want there . Technically its not a dock and if you want apps like phone on multiple screens you just repeat the shortcut.
