Gnome Panel is a component that is part of GnomeFlashback and provides panels
and default applets for the desktop. A panel is a horizontal or vertical bar
that can be added to each side of the screen. By default there is one panel on
the top of the screen and one on the bottom, but this is configurable. The
panels are used to add applets such as a menu bar to open applications, a clock
and indicator applets which provide access to configure features of the system
such as the network, sound or the current keyboard layout. On the bottom panel
there is usually a list of open applications.
