How does one enable the Quick Detail Page?
The Quick  Detail page (QDP) can be turned on for the entire subscription or just for you. To check if it is turned on, navigate to the avatar and click My Settings, then click Labs.  Look for QDP View Modes.  

The Quick Detail Page (QDP) is the default for portfolio items, defects, user stories, test sets, test cases, and tasks. If this feature is turned on, all you need to do is click a formatted ID and a panel slides out from the right side of your window.
