I see a number of suggestions for enabling secondary sort or other ways to give sort order more finesse. One very simple way would be to stop putting blanks at the top of sort order. When I want to sort a least of features by release date, I really don't want the parking lot items at the top. However, I don't want to filter them out either. So, if the natural sort order didn't assume that blanks above populated items, that would solve my problem.
