Would a magnification function be helpful?
Analog Instruments (Phillip Smith's firm) sold expanded Smith charts of 3 kinds: expanded about the center with two magnification factors IIRC, and expanded about the high- and low-impedance areas, the latter two for working with open- and short-circuited stubs respectively. They also made admittance charts and charts with negative real part, for parametric amplifiers, oscillators, and the like. I have samples of most of them in a tote somewhere......
I suspect that the expanded-center function would be most useful for the majority of the users; I doubt that anyone is doing graphical solutions of stubs any more..
