Maybe late to the party, but can’t our WindowBuilder already do multiple windows just fine? (with an XMl driven UI, though : that’s the aprt that is missing to make it useful at runtime)

I think extending WindowBuidler to allow changes at runtime might be a better solution than using osgCompositeViewer, becuase this will keep existing multi-window / multi-view setups working. My guess is if we switch to osgCompositeViewer, we might break some of those.

Kind regards,
