One of the strenghts of PlusDock over other docking packages available today is the skinnable model. The skin is provided through the DockTheme class. The DockTheme class has a property for each of the elements compising a model (toolwindows header, footer, body, document windows header, footer, body, and so on.). Each property can be set individually offering an extremely flexible skin model. And all can be done at design time as well as at runtime. As a matter of fact, the DockTheme comes with an internal mechanism that allows saving and restoring of the theme straight from the design time, so you can define your own themes, save them and include them in your binaries.
