The first entry (Smith-Chart Diagram) under "Particular Interests".

> Automated matching, with options to make a trade-off between bandwidth and
number of components for example, would be quite useful I think. Graphical
aids are more complicated probably, but at least having functions to
compute stability, VSWR, etc. for a given network and then plot the
contours in a Smith chart wouldn't be hard I think.
