How I can customize OS X 10.5 dock?

It would be an under statement to say that very few users were unhappy when Leopard (OSX 10.5) changed the style Dock. Since then, a wave of software authors have come out with programs to modify the appearance of the Dock. I tried several of these programs,and have become a winner - SuperDocker. And as an added bonus, it has a number of features that are not related to spring, but there are super helpful. Oh, I should also mention, SuperDocker is free (actually donation-ware, so if you really like, do not consider donating).

SuperDocker is available in English, French, Dutch and Italian. Installation is as easy as dragging SupperDocker to the Applications folder. Launch it from there.

The first tab, Dock, is where you can do most of the customization of your Dock. You can change the style 2D 3D Dock, change the icon transparency, add separators, and even change the graphical style springs.
