eh, I think spice is always going to be one of those things that takes
some learning. An IBIS tool would be a much better match for GUI
integration.

For me, the most non-intuitive things were the naming of the '0' net
and the use of the tran command in ngspice, past that, everything was
pretty intuitive. One of the problems is the howto is more of a
manual:

A tutorial with an example design would be of enormous help. A nice
example might be an unterminated vs terminated transmission line.
