This feature allows you to trace all changes made to the project. Every change, made by a member of the project team, is recorded in the timeline, when the project is saved. It provides you with the information about all changes with project name, time and description, with the hyperlink for the attached documents, etc. The timeline helps you to stay up-to-date, special when several participants work with the same project.
