Comment 226 for bug 668415

@danillo; no because it introduces far too many bugs in multiple areas of the interface. A lot of the interface has been both designed and built around the concept of a launcher on the left hand side, and supporting multiple launcher locations in a official release would incur a significant extra ongoing cost (both design and development wise), and we are currently focusing our limited resources on stabilisation and some brand new features ;-)

However there is a unofficial patch that moves the Launcher to the bottom, see http://www.webupd8.org/2011/11/install-ubuntu-unity-bottom-launcher.html Generally I think this is the right approach, work to raise the quality bar of the official version of Ubuntu, and features and customisations that some people want but which do not meet this quality bar become available as 3rd party extensions.
