After running a search in the staff client or OPAC, there is an "Availability" option at the top of search facets that allows you to "Limit to records with available items." Some libraries have bibliographic records without items attached that they want to show as available (electronic resources, for example). It would be helpful to have the ability to hide this availability toggle with a system preference. Even better would be the option to hide in the OPAC but not in the staff client, if possible.
