Hidden feature: Secondary sorting

UPDATE: This can now (v5.1) be done "officially" in the "Mix" options -- see here.

With the new Limits feature you can apply a secondary sorting criteria, as this example shows:

1. Set Play Count as primary sorting criteria ("Sort 0...n ⇣")
2. Set "Limit list to 9999 titles", selected by "least recently played"

Like that the titles will be ordered by Play Count, and within the same Play Count they are ordered by Last Played, with the least often and least recently played songs on top.
