So I, like many others, use org-mode to implement GTD to manage my life. One thing that happens since I'm in school is long-term projects, which have milestones. In and of themselves these milestones are strictly sequential events, and within these milestones even usually there are strictly sequential events.
As it stands now, I mark all the items that are blocked because of the current
TODO. Whenever I finish a task and mark it
DONE, I have the mental burden of then reviewing my project support materials to determine what becomes the new
NEXTACTION. This is fine, but inefficient if I already know the order of events. Is there a way to automatically change the next item down (in a list, actual next line, any way) to
NEXTACTION when I mark an item
