Comment 75 for bug 668415

"I think the report actually meant that the launcher should be movable to
other edges of the screen. I'm afraid that won't work with our broader
design goals, so we won't implement that. We want the launcher always
close to the Ubuntu button.

This 100% makes sense as you would have to move the mouse to the left screen to enable the launcher then move the mouse to the right to click things on the menu.

Thus we need functionality to move the ubuntu button AND the launcher to the right side of the screen. The specific use case where this is required is if you have a screen to the left of your main screen. You are unable to move the mouse to the left screen to bring out the launcher, as the mouse goes onto the left screen.

The other alternative is to prevent any screen other than the default screen from being on the left side of the desktop.
