...should NOT cover up this top nav...
Why? Because the top nav provides much of the main functionality that you can do on the page. It keeps happening that I waste time looking around for how to do something -- but it's hidden from view, because I had not first selected a record. (As currently designed, the top nav only appears once you select a record (an LP) from the list.) One shouldn't have to select a record in order to see & understand most of the functionality available on the page.
