Hi, I want to do automatic updates via the update manager in both the zoomwindow as in the application window. Can I do this in 1 step or do I have to perform the update (dom manipulation) in both updatemanagers of the JSVGCanvas of the application window and the one of the zoomwindow?

There is no real reason you couldn't change this although it would be a non-trivial piece of work.
