Making parallel tasks work like buckets makes the most sense to me. I.e., just eliminate the distinction between "available" or "next" or whatever. Parallel tasks are all next actions (because any one of them can be done to move the project forward) and only the first action of a sequential project is a next action.

I was surprised to see the distinction when I first used OmniFocus... it does not help to "get things done". Yes, you can differentiate between "unrelated single actions" and "related parallel actions", but, honestly, so what? They will all get checked off soon anyway (well, hopefully :-).

I would definitely not want to see more pref bloat for such a minor thing, though.
