Show Great on Deck on Steam is a Firefox extension designed to improve the visibility of Steam Deck Verification Status for games on the Steam Store. It addresses a common issue where the verification status is not displayed on all pages, allowing users to easily identify which games are compatible with their Steam Deck at a glance. This functionality enhances the browsing experience for Steam users who own a Steam Deck, making it easier to find suitable games.

In addition to displaying the verification status, the extension ensures that users have access to the most current information by adding a medal from ProtonDB to search results, as well as the front and app pages. This feature guarantees that users are informed about the compatibility of games with the Steam Deck, enhancing their gaming experience and decision-making process.
