I write most text using org-mode nowadays, and I often use it to generate PDF via LaTeX (xelatex, specifcally). But now I want to use it to write scientific articles, and journals often want me to use a specific style. This includes a .cls-file, which is easy enough using org-latex-classes, but quite often, they require a specific setup following \begin{document} (i.e. a specific abstract section, funky author and affiliation, etc, and I don't see how to do that. That is, I now do this within a #+begin/end_latex section - but this needs to be completely rewritten if I switch style.
I realize I probably need to fiddle with the LaTeX code at some point, but I'd like to minimize this fiddling as far as possible, and I'd like to be able to switch from one journal to another with a minimum of fuss, and keeping my org-mode source as intact as possible.
