I'm impressed at how the new footnote support has
managed to put together readability, stability, ease of use and
export-ability (including the ability to refer to a footnote multiple
times!) . I have seen no problems in my initial tests, and will do
more extensive (can I break anything?) tests as soon as I have the
chance.
I think that 'org' is now the only plain-text minimal markup engine
to support both inline and out-of-line footnotes, and I'm quite sure
that none of the others have numbered, labeled, and inline footnotes.
And as for ease of use, well any comparison is unfair. The rest are
just language specifications and processing engines, they offer no help
in the writing.
I'm shocked and pleased at how Carsten (with input from the
contributors to this thread) managed to make a somewhat ragged and even
contradictory wishlist into something this elegant and easy to use.
