A common request for previous versions of Project Server was the ability to extend the security timeout of pages within the tool. Why this was requested was users typically started an action, got called away, or popped out for a coffee, then came back to the page they were editing, pressed save only to be told that the page had timed out and all their edits had been lost. Now this was not across the whole of tool, but only certain pages like editing views, SharePoint team sites etc.
