The project timeline shows you all the projects that have due dates, and task and to-dos with due dates. On the left side you'll see all the projects and on the right the timeline with dates.
By default you'll see the current month with all the projects. You can zoom in to a week view or zoom out to 3-month view. This lets you focus on details or get a bigger picture of your timeline.
The project timeline is automatiacally updated when you add or update dates.
You can drag and drop to change dates, resize the events to shorten or lengthen them. All the other standard filters and bookmarking also work for the project timeline calendar.
