One last feature item. If we had a system like the one below, why not include the option to author e-mails as an outline? It would make it easier to organize thoughts and annotate replies to e-mails received in outline form. Imagine a lawyer or doctor working with a tool like this. Drag and drop some outlined case law or medical text info, annotate it, and send it as OPML. It also offers up some interesting possibilities in automated mergers of annotations from several sources into a single outline (for an RFC, class notes, etc.). [John Robb's Radio Weblog]
