i assigned a theme (officeBlack) to my dockingmanager. Very nice. Not so nice is that the floatingwindows dont apply this theme. is there any way to do that manually?

By default, a floatingwindow will use the os non-client area as occurs with VS. You can handle the ToolWindowLoaded event of the xamDockManager and set the e.ToolWindow.UseOSNonClientArea to false

another thing is that it would be very nice if the floatingWindow could be maximized in any way. we work  with a multi monitor application. so the floating window could be maximized on the second monitor. is this possible?

. Currently maximizing is not support. You may want to submit a feature request for this.
