Good evening,

I agree. What I meant was that if protruding of drop caps was possible,
one could use the function manually, and protrude the drop cap by trial
& error until it appeared optically aligned in the output.

Personally, I think a foonote ref on one page and a footnote on the next
is more obtrusive to the reader than a page that is hung, but other
people may have other opinions.

I found this in the archives, written by you last year (I think):

"However, no cross-reference facilities.  I've given the matter some
thought, but have yet to come up with a way of implementing them in
mom [...}"

Still true?
