I love everything about LaTex Tidy except for the fact that it puts \labels on a separate line to \begin or \end, so when I use code folding all I see is a list of \begins, \ends, \sections and the like, without a \label in sight. Rene pointed me to latextidy.pl, which was the help I needed, and I hacked the file so the code now ends

I’ve allowed for optional arguments on \labels, labels pinned to \end (for captioned environments), and insert blank lines before \sections and \subsections. Now when I code fold I see not just the environments but their \labels, which mean something to me.

thank you very much for looking into this. I would be very interested in merging your changes! Can you please open a pull request [1] containing your changes at the official GitHub page of the LaTeX bundle [2]?
