I got the CLI-view-launcher demo test to work fine on a debian unstable installation.
The script to generate various kinds of sim run results windows is
just text, to quickly set up what you want.  The Matplotlib this is
based on seems very complete, so maybe all the wish list functions
can be done easily.

The GUI-view-launcher demo test stopped without running the script because I didn't
understand where the command line was.  It's not in the area that looks like a terminal window,
but in a text dialog box below that at the bottom border of the window.

When I got that right, it runs a little differently, it waits until the command

to run the simulator, then puts up the 5 various window displays as in the
CLI-view-launcher demo.  The command window shows progress as below:

Each of the windows has pan, zoom, a list of right click options to change
that probably comes from matplotlib.  My first exploration of pan did some good,
but right mouse zoom, (as documented by hover mouse help popups),
got the whole app to freeze.

Pretty good overall!  I'll help test this further Ivan and Arnaud.
