First off, I view Projects and Tasks completely differently. Tasks are what you need to accomplish for a given project and a project is a collection of tasks. Projects usually do not have any tie-in to other projects, so they should be set to parallel. The tasks, for me, are what I would like to determine are either parallel or sequential. I think that I would rather have tasks be parallel by default (just me) because many of my tasks in a given project can be done "out of order". Then for the ones that would need to be done in sequence I could just change it over when I needed to.

Now, if you are talking about sub-projects, that is a different story. I think sub-projects should be sequential by default but the tasks, again, would be parallel by default.

Hope that this makes sense and is in line with what you are asking.
