Here is a view of my Workspace Switcher. As you can see, I've moved my dock from the left to the bottom. If you look carefully, you can see that the black strip left for the launcher. Is there a way to remove this and move it to the bottom? I want it on the bottom rather than removed totally because clicking back on the Switcher icon moves me into workspace 4.

This is not true unity; rather it is using the CCSM plugin "Ubuntu Unity Plugin Rotated"
