The current release of the code doesn't really support this but it's
one of those easy-to-add features that make sense to me. I just
checked in some changes to the drawing code so that it supports the
ignoreHs argument:

[5]>>> Draw.ShowMol(mh,ignoreHs=True)

or:

[6]>>> Draw.MolToFile(mh,'blah.png',ignoreHs=True)

Best Regards,
