"In Cinnamon 1.3, every panel component is an applet. This means
you can remove the default menu or window list and replace them
with 3rd party applets.
Another important feature in this release, is the fact that
applets can now be dragged and dropped with the mouse and placed
wherever you want within the panel(s). So you can now move any part
of the panel(s) around and really fine-tune the layout of your
desktop to what works best for you.
