Chromebook apps launcher moved and position of the launch bar is adaptable now

In the recent stable chromeOS release 31.0.1650.61 (Platform version: 4731.73.0) the apps lanucher button moved to the left and the whole bar is now movable (left, bottom, right). Now the windows users will not search for the start button anymore :-)

See the screenshot below of my launch bar after the update.
