All the Panels in Productioneer (such as the list of Fields, Reports, Information, etc...) are equipped with an auto-hide feature that hides the panel out of the way while not in use.

To active auto-hide, unpin the pushpin on the top right corner of the panel.

When a Panel is hidden, clicking on its title will bring it temporarily into view. To keep the panel from auto-hiding (pinned) click the push pin again.
