Facets on the left sidebar of the OPAC currently sort alphabetically. It would be nice to allow administrators the option to order them by number of results, with most hits at the top of the list. I understand that this, like the displayFacetCount preference, would be highly dependent on the value of the maxRecordsForFacets. Still, this type of sorting for facets is common in discovery systems and, I think, something our patrons expect.
