I recommend you use the Elfsight Restaurant Menu widget (https://elfsight.com/restaurant-menu-widget/) and simply integrate it with your digital signage, learn how to here; https://playsignage.com/support/menu/#get-started
Hi @NextGenAds . You could create one or more playlists and place the slides you want to save in there. You'd do that with help of slide stash (temporary holding area). You could also put those playlists in a folder to keep them separate from other playlists you use daily.
