An arrangment option that was random. This is a feature that Iview media allows. You simply hit view by random and the images are set in random order. You can hit sort again and they are again sorted randomly. This is a nice feature when you want to crate a quick slideshow but don't necessarily want the images to appear by capture date. I know you can have a slidehow go in random order but you can't export the slideshow. It would be nice to be able to apply this random order in a contact sheet. From there you can rename and keep this new order if you like, by later sorting by file name.
