@laritakr I'm wondering, did you explore arranging facets in the catalog controller?

https://github.com/scientist-softserv/west-virginia-university/blob/fbb244d55195e58a0cfb863a84229f3e3c8515cc/hydra/app/controllers/catalog_controller.rb#L50-L66

My understanding is the order in which they are defined is the default sort order. Which would then remove the need for a decorator.

I thought about doing it that way, but I thought adding the explicit sort made it more obvious and less subject to someone changing it inadvertently. I can do it the other way and just comment it, if you think that's better.
