Comment 3 for bug 1911940

A related feature (also inspired by OverDrive's curated collections) -- we'd like to also be able to have an option to show all the titles, but give priority to the titles with available copies. Although this would still look like just a single stream of titles, the order would be Available in Random order, followed by Not Available in Random order. (These should be two separate settings, so we can mix or match depending on the project.)
