Based on posts here I found the "Task-focused API" http://en.wikipedia.org/wiki/Task-Focused_Interface . There are lots of extensions available based on it: http://wiki.eclipse.org/index.php/Mylyn_Extensions . For example, from gmail, you can add a task by tagging a message! This Extensions page also seems to be a good reference list of todo aka project management trackers.
