Pros
Pro Offers lots of granularity in task management
Tasks are grouped in task lists and can have subtasks. Each task list can be assigned to a particular set of users, aligned with a milestone and have notes. Each task in the task list can have a description, a start and a due date, attachments, priority, manually set progress, followers, dependencies, be assigned to a particular set of users and set to repeat. Each subtask has the same configurable properties except instead of the ability to assign people, subtasks can be commented on.
