|132||140|| * Query about parents, blockers, milestones. These features do not seem obvious. Blockers has a name sufficient to suggest task dependencies/prerequisites: how are they modeled & what consequences ensue? (A pet peeve is that IMO "blocking" should ''preclude'' work on the downstream task, else what's the POINT of the relationship? ''Parent'' meanwhile suggests heirarchy or abstraction, but again I don't see the connection to any consequences in operation or display. I guess this is a documentation request.
