JCP now has minimal lone pair display. I would prefer the layout to be at the corners of a square, rather than on the edges. Videlicet, they are currently only at N, W, S, E; I think that NW, SW, SW, and NE would be better.
Strangely lone pairs don't seem to appear in CML files when written out, but Egon says he will look at this. Perhaps I should file a bug report...
Oh, and radicals are implemented too,
but I don't have a picture of that (see right). They are in different generators, but I guess a single 'DotGenerator' could do both :)
