I'm currently writing a thesis. Just the introduction is 25 pages/8000 words. The whole document will probably be 70 pages or so. With a document this large, and on such a complex topic, it can be quite hard to keep track of what's going on where.
I'm looking for ways to summarise the document structure, that might make it easier to figure out what needs changing. Things like lists of topic sentences and signposts (possibly marked as such in the code); word, paragraph, and image counts per chapter/section/subsection; visualisations of flow; plots of keyword densities and readability; and so forth.
What types of tools are there (aside from the ones I mentioned), and what software implementations are available (including for the tools I mentioned)? Answers that deal with non-computer based visualisations (e.g. sketches) are also welcome.
(Note: I asked this on Tex.SE, but I think that the question is too specific for that site.)
