Great. Now, for option #3, which I forgot (and someone graciously reminded me
of via email):
3) Trash the individual groups via active file type-x entries.

This is likely, at first guess, to be much closer to #2, but I'm not sure it
wouldn't still be a bit slower. It also has the double-edged "feature" of
requiring you to x-ify each new subgroup as it's created. So you need to
intervene by hand. On the other hand, you might decide you _were_ interested
in that particular sub-group, after all.

Thanks,
