I've posted the s-parameter Smith plotter here:
Please read splot.txt to learn the obscure tricks (like how to display a Smith plot!). I will try to free up some screen space for a dedicated Smith button.
I found so many bugs today and of so many kinds that I'm sure there must be some left. Please email if you spot something amiss. My email address is at the bottom of the page referenced above.
When I post a new version, the image at the top of the page will have an updated version number (it's in the upper left). You may have to Ctrl-refresh your browser to refresh your image cache.
