For me, one of the important parts of GTD is the idea that if you have a Project, there should always be at least one Next Action associated with that Project in your lists of tasks to do. For instance, if you had 20 active Projects, I would expect that the there are AT LEAST 20 active tasks (plus there may be some active tasks that are simple enough not to be associated with any project.)
So, it seems to me that software that supports GTD should have some really obvious way of letting me know which Projects aren't currently "represented" in my tasks lists. But, I haven't found a single web application that works that way. Does any GTD software handle this?
Thanks for advice! -Steve
