I recently read this argument about why syntax coloring/highlighting is not useful when writing code. The article featured this image of syntax-colored English text:
While the article argues against the readability of this text, I actually think it could be quite useful for writers, for instance to make sure they don't overuse the same verb or use too many pronouns. So I was wondering if there was any software that provides syntax coloring for the English language.
Such software should be able to detect parts of speech (such as nouns, verbs, adjectives, etc). Detection for things like comment-like breaks-- for instance, this section here-- or quotations would also be appreciated, but not necessary. The best answer would be the one that offers the most complete solution, as I do realize that fully implementing this idea would be nearly impossible due to the complexities of the English language.
Cross-platform would be nice, but I'm looking specifically for something that works on Windows.
