I think Miles has the right idea.  Allow windows to be opened with various
degrees of opaqueness.  The application running underneath would still be
visable so the user could be receiving info from both programs.  Imagine this
: you are displaying a digitized or raytraced picture and you want to look
at the CAD description of it, your engineering notes, or a structural analysis
of what ever you are displaying, so you open a transparent window on top of
the picture.  You could see important differences and make changes accordingly.
You could open a drawing program in a transparent window and sketch an outline
or addition to the original picture, without touching the original.
 
	CBM please include such a feature in V1.5 (1.4 would be even better).
