I am trying out Ubuntu Linux and one thing I really want to change is the change is the default theme.  I saw the a theme site and saw a really good menu bar and thought that downloading the theme would allow me to have that look. But, the theme only change the color. Can anyone tell me how to change the look of my menu bar to look like the picture below?For reference, I would only like to have one menu bar and not 2.
