Org mode does not require TODO lists to live in separate documents. Instead, TODO items are part of a notes file, because TODO items usually come up while taking notes! With Org mode, simply mark any entry in a tree as being a TODO item. In this way, information is not duplicated, and TODO items remain in the context from which they emerged.
