This request concerns adding a state for the buttons in the ToolWindow caption, which will allow different theming for the buttons, when the window is active and inactive.

One should know what is the reason that causes a transaction to take place. For example, if you double-click the titlebar of a FloatingWindow to redock it in RadDock, the user should known that the reason is a double-click operation.

Currently, loading the store layout in RadDock may result in different UI panels according to the available internal splitcontainers/panels that are invisible. Perhaps a "SaveAsDefaultLayout()" and "RestoreDefaultLayout()" method could be introduced. Thus, it wouldn't be necessary to clear the windows before loading XML layout.

There should be a method which hides/closes (depending on the CloseAction) a DocumentWindow. This method should be called from the DocumentWindow instance.
