I am a new user of DevonThink (and DevonAgent), and really amazed with it.
It is a great tool for research and for writing. And also for organizing online courses (with WEBCT or other course management software). I think it would be helpful to have an interface with some of these programs (possibly the opensource ones, like ATUTOR or MOODLE) to be able to create course material from your DT database and put it online smoothly. What do you think?
