The Feature Guide
Tasks on the Run offers more advanced tracking tools, but for a lot of projects the basic tracking provided by milestones and groups is all that's needed.
You can start by viewing all the milestones or groups in a folder. In the case of milestones, they get ordered with the soonest due dates first, and for each milestone you can see a progress indicator.

When you drill down into a milestone or a group, you can see all the related tasks as well as a visual bar graph for the progress.
