I'd vote for sequential. I think that would be more sensible as a starting point.

As long as a person has the ability to easily designate parallel or sequential then that's the main thing.

This may be a silly question, but wouldn't it be possible in the general Preferences for the program to set what each person's general preference is (sequential/parallel)? Then they could change from their designated preference as needed when working on new projects?
