Is it possible to show the headers of all subfolds under their respective parent folds in vim? This would be incredibly useful, for example when writing latex, where the document may have 4-5 levels of folds, and you want to get a quick overview of the outline. For example, it would be nice to see output like this:
2 +--342 lines: \chapter{Methodology}--------------------------------------
6 +---210 lines: \section{some section}------------------------------------
46 +---- 12 lines: \subsection{some subsection}-----------------------------
58 +----158 lines: \subsection{some subsection}-----------------------------
216 +---197 lines: \section{some other section}------------------------------
279 +---- 42 lines: \subsection{some other subsection}-----------------------
and, ideally, to be able to open and close those sections without opening the parent section.

You can define your own function to show the fold text that you prefer and set the
foldtextoption to it. See:help fold-foldtextfor an example. – Raimondi – 2012-06-18T04:37:55.660Thanks for the pointer @ElIsra, but I'm not very familiar with the vim language yet. I'll see what I can do, if I find time, but if someone else posts such a function, I'd probably accept that answer. – naught101 – 2012-06-18T08:04:38.327
The problem with your idea is that subfolds, being contained within other folds, are not supposed to be visible at all. That's the point of a fold: closing a fold hides everything within this fold's boundaries. Are you looking for an outlining system?

Also, VOoM doesn't appear to like partial latex files (I submitted a bug)
