Docker allows Leopard users to switch between 2D or 3D dock, or customize the Dock further by individually changing the color of and style of Dock parts. If you are feeling creative, you can easily select your own images, or a vast array of styles available for download.
Docker also lets users of OS X 10.2 to 10.7 and later access settings normally hidden out of sight. Choose from a larger range of dock sizes, extra animation options and more. Docker now also includes options to prevent users altering Dock settings and contents and an option to hide or remove the menubar and dock.
