Subject: Add the ability to remove a toolbar from the unified toolbar.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This allows to toggle the unified look of the
toolbar. This is useful for apps going fullscreen
since we have to turn the unified look off when
entering fullscreen mode.
