Abstract: A computing system generates and displays a comparison task list that reports differences between a source task list for a project and a modified task list for the project. The comparison task list may enable a user to determine the implications of changes to the project by providing a comparison of the source task list and the modified task list. The computing system generates the comparison task list by generating the comparison task list as a copy of the source task list. The computing system automatically adds each task item in the modified task list that does not have an equivalent task item in the comparison task list to the comparison task list at positions that depend on whether the task items have previously-processed sibling task items in the modified task list. When the computing system has processed each task item in the modified task list, the computing system displays the comparison task list.

Abstract: A timeline is generated from and fully integrated with a project schedule. The project schedule may be any graphical representation for displaying detailed information associated with a project. The timeline visually represents certain tasks, dates and other information associated with the project schedule such that an overview of the project schedule may be determined.
