I am writing my doctoral dissertation in Latex, so I have to rely on a Tools such as Copywrite or Ulysses to organize my text. Ulysses is way overpriced and does not have folder organisation (only one level of documents), but it can export into Latex, plain text, and other formats. So I purchased Copywrite, because it is reasonably priced, has a great interface and full text mode, allows for good organisation with modifyable keywords / folders (=categories), but it has A VERY VERY POOR EXPORT! I don't want to be locked into rtf (Mellel also does that to you) and the Copywrite file format! Also, Ulysses stores information in plain text which is much more secure and transparent! So PLEASE, put text only export in there FAST, and without strange additions like a header on each site and a ------- to mark page breaks!
