I know of no better tool for writing. From research, assembly, resequencing, formatting to final publication, look no further. I have abandoned any and all “word processors” in favor of this app. We would all be much better off if the ancient, paper constrained, linear document concept were totally replaced by outlining and this is “best of breed”. The catch phrase: “The index is the document and the document is the index.” applies here. Now, if HTML5 would only support OPML cross platform blogs and websites, I would be in heaven. All blogs and websites would do well to use this as a simple, consistent means of navigation, providing optimum use of screen space and minimizing the need for links and scrolling.
