The ability to show the detailed listing from a dynamic custom view on a separate page would be very very useful. This would allow the detailed listing to use a page different template than the list of entries.
This would also allow multiple dynamic custom views to be shown on the same page without the problem of the list of entries “unused” dynamic listing showing up above or below the detailed listing you’re currently viewing.
You could add a dropdown to the “Advanced” section of the Edit Custom View page that shows all available pages. The default would be “Same page.”
