I just got a bug report for
multicol because of a strange white space at the top of the first column and I traced it to the use of the
pdfsync package that added material in various places that did somehow conflict with the column balancing routines of
Now this is rather an issue with this particular package that adds material in a way it perhaps shouldn't (well it warns that this could happen and that it should never be used on final documents). But it makes me wonder if there are any useful applications for this package at all these days, given that you can get this functionality (at least with TL binaries) by specifying
-synctex=1 and use editors like TeXWorks without any side-effects.
If the answer is yes it is needed, which are those applications? If no, shouldn't the package get a bold warning (say, via
\typeout) that it would be better to remove it and rely on a different approach?
Even if the answer is yes, I think a
\typeoutwarning would be in order that it shouldn't be used on final documents (as the author states).
