One very usefull package is the
hyperref-package. However a lot of times this package interferes with other packages or structures within a LaTeX document.

N.B. I have not added any specific example, because I think most of you know what I mean. For example: it very often happens that people answering a quesion write
Does (not) work with
even though the OP never mentioned the package in his question. This suggests that
hyperref is indeed something special.
