Even more is missing to make it approach the quality of the ancient graph
browser by Stefan Berghofer from 1996: it lacks the important "rubberband"
phase to get the layout straight.
The Swing/Scala replacement was added too early to the Isabelle code base,
expecting that it would become better before the release, but it probably
means that I have to finish it myself if nothing happens: removing more of
its experimental features and recovering functionality that was
common-place in the 1996 version.

You can do it like this while Isabelle/jEdit is running:
Unsynchronized.change print_mode (remove (op =) Graph_Display.graphview_reportN)
