From the developer:
If you think that Snow Leopard's Spaces feature is cool, you will love Dock Spaces. You can have up to 10 Docks and organise your applications as you like. Once you create and name your Docks you can swap anytime you want from the menu bar or using shortcuts. Furthermore, you can assign a Dock to a Space and take advantages of Spaces in a more fantastic way. It has a very simple interface and it is easy to use.
