I have tried and thought about many things until finally writing my own tool that is extremely fast, powerful, and flexible. Currently it could be seen as org-mode replacement that addresses some of the key challenges (hard to learn, awkward) while keeping some key benefits (efficient from keyboard, extremely flexible), and adding huge flexibility in what can be done: <a href="http://onemodel.org" rel="nofollow">http://onemodel.org</a> (AGPL).<p>It is a personal organizer, is something like really fast mind maps but (currently) keyboard-driven and handles very large amounts of interlinked data, different topics at once or mixed etc: the beginning of a platform to change how individuals (or mankind) manage knowledge overall. Future features involve much more than note-taking, but exploiting the internals for collaboration, anki-like repetition, to-do reminders, and more.<p>For current org-mode or evernote users: The app has export (& import) features to convert anything to (or from) an indented plain-text outline. The FAQs have links to a discussion of a more detailed comparison with org-mode that seemed somewhat well-received at the time (link is on this page which discusses evernote: <a href="http://onemodel.org/1/e-9223372036854614741.html" rel="nofollow">http://onemodel.org/1/e-9223372036854614741.html</a> ).<p>Feedback would be much appreciated. If one has any interest at all, I suggest signing up for the (~monthly?) announcements list, and participating in discussions on the general list, for suggestions & input on things going forward.<p>(Ps: in the next week or less I hope to have a demo version available to play with easily, without having to install anything first but the .jar.)
