I would like to be able to a diagramming tool's main window over another application's window, so that I can trace areas from the base window with drawing elements on the overlaid window. I can take a screenshot of the base window and use it in the bottom layer of a diagram, but that brings the risk of building diagrams off an out of date base image, and I could even automate the update of the base image when I start the diagramming tool. Both of these seem a bit of a kludge compared to synchronising resizes and moves on both windows and one with a transparent background.
