Shoppers who open a product and want to see the next one usually have to go back to the collection and find their place again. Product Nav by Gizmonger adds previous and next product links to your product pages, in the order of the collection the shopper came from, and a button back to that collection. Add it from the app's dashboard in one click, then change the style, labels and phone layout in the Editor.
