Definitely this (AGPL): I heavily use a tool I've mentioned before, which I wrote (after trying org-mode, collapsible outlines in other tools, etc). It uses postgres, and I hope that "sharing" data exchange features are coming (though it already does export to org-mode-like text, and to html). Best code is that in github, though a downloadable .jar is available. Currently keyboard and desktop-only (text-oriented). The most efficient/effective thing I have found for notes/lists/details of all kinds, and should be easy to learn to use, as all the essentials are on the screen. There is a tutorial. [updated, to add:] Part of the eventual purpose of the tool is to help individuals and mentors via maturity models that apply more generally to life before getting into any particular topic. That could easily be misunderstood, and there is more about that at the web site (below). Part of the idea is to help in the development/growth of self and others -- skills, knowledge, positive character traits, anything good -- in any area of life that one chooses, so we can have good goals instead of trying to make life seem fulfilling with empty searching for more pleasure/power/attention. By marking things done or "archived", it also provides a journal feature or personal log, of entries created or archived in any date range (defaulting to "yesterday and so far, today", to help with daily standup reporting). http://onemodel.org http://onemodel.org Feedback welcome.
