The Xfce 4 Panel supports multiple panels, with many options for their position, appearance, transparency and behavior. There are many items available by default to full fit a panel, like application launchers with detachable menus, a graphical pager, a tasklist, a clock, a system tray, a show/hide desktop switcher, and even more. It offers an easy way to add items using a dialog, and to move items accross different panels.
