I assumed that, while GTD was a major influence, there was some interest in accommodating other systems or procedures as well. Dogmatism about to-do lists strikes me as a little over-the-top.

I don't know whether I'd actually use a thing like this. My usual thing, if I call someone and miss them, is to assign a start date to calling them back. If I don't hear back, the system works as expected; it shows up on my list again. If I do hear back, then that's my trigger to go update my list as I'm working on whatever I had to hear back to do.

But I think it sounds like a pretty good feature to have an intermediate state; possibly "in progress" tasks could sort at the top or bottom of the list in Context view. If you don't use it, no problem.

It seems like a good software feature, simply because it's extremely hard to emulate without the feature there, and very easy to ignore if you don't need it.
