    <para>A panel is an area in the GNOME Desktop where you have access to certain actions and information, no matter what the state of your application windows. <!-- The HIG says 'Do not use system modal windows', so panels are always available. --> For example, in the default GNOME panels, you can launch applications, see the date and time, control the system sound volume, and more.</para> 
    <para>You can customize panels to your liking. You can change their behavior and appearance, and you can add or remove objects from your panels. You can create multiple panels, and choose different properties, objects, and backgrounds for each panel. You can also hide panels.</para>
    <para>By default, the GNOME Desktop contains a panel at the top edge of the screen,
and a panel at the bottom edge of the screen. The following sections describe
these panels.</para>
