DockExtender allows you to minimize dock clutter by allowing you to create DockExtender Menus that fit right into the dock or quickly access them through a menu bar tool. These menus contain lists of programs that are completely configurable by you. This greatly enhances the clean look of the dock, and improves speed and usability of the dock.
The DockExtender menu bar tool also allows you to create multiple docks on your system and switch between them easily.
Configuration takes place through the system preferences application right beside all other user preference settings.
