DrXym writes "GNOME Shell has been criticized for certain shortcomings when compared to GNOME 2.x. Chief amongst them was that 2.x offered panel applets whereas 3.x is seemingly lacking any such functionality. What most people don't know is that GNOME Shell has a rich extension framework similar to Mozilla Firefox add-ons. Now, the official site to install extensions has gone live. So if you yearn for an application menu, or a dock, or a status monitor, then head on over. Extensions can be installed with a few clicks and removed just as easily."
