I'm slightly confused as to what the difference between the single task setting and the parallel setting in project mode. I was just curious as to what circumstances you guys would decide to use each.

Also I can't seem to be able to work out the difference between a task in purple and a task in black. As far as I can see both have the same complexion in terms of due date, project, context ect. I genuinely can't seem to find one difference and yet one obviously exists!

A OmniFocus elder's assistance would be more than appreciated.
