Additional Details/Fields in the main project/task window

Our group is asking about some of the reportable fields and why they cannot turn them on to be visible in the main project or task window. For example - they want to be able to see the Author, Created On, and Completed On Dates in the main project window. Right now, they can only see them in reports and table view. We should be able to turn on some of those additional data points to be visible in the main project window.
