Search by game I'd link added to games wishlist page.

You can't click on the name of the game and the URL below it goes to the Steam store page. There is a magnifying glass icon next to giveaways and if you click it, it will search all public giveaways for that game and show you all the current giveaways for that specific game. They want that magnifying glass feature next to each game on the community wishlist page.

It seems that you are using ESGST and have Community Wishlist Search Link activated. It turns the numbers in the "Giveaways" column of any community wishlist page into links that allow you to search for all of the active giveaways for the game (that are visible to you).
