GNOME Panel Customization

[Jake <jakamoonzi aol com>]

Hello,
I have recently found out that it is possible to customize the GNOME Panel. That is what I use as I don't like GNOME Shell. I've tried using Alt+Right Click, but it doesn't work for customization unless on an existing applet, which only lets you change it for that specific things, such as the name of the launcher. How can I change the Panel?

Thank you!
