If you already have the Hibernate Configuration view open to see all the Class objects available, and the HQL editor open (the HQL/JPA-QL query you want to optimize), and have the Dynamic SQL Preview view open to see the actual query, I was kind of hoping to just add to the Hibernate Configuration view (that you may already have open) that index information in its Database tree node.
Just seems like keep adding in more views/swapping to more tools (such as a DTP view), when there is an opportunity for improvement.
