Displays Hidden Products

Love this plugin first of all. Discovered something recently that may want to be addressed. I market some items in private (as hidden) and do not want them showing up on the site. The plugin is displaying hidden products. Seems like this should be a settings option or minimally told not to display hidden products. I know this plugin has not been updated in some time. If it is not possible to update -perhaps someone would be willing to share a code change I could use to fix this manually?
