Can Shopper and Stock Remaining Counter be set to appear on only specific product pages?
No, Shopper and Stock Remaining Counter does not yet have this functionality.
A workaround would be to use the Custom CSS field in the app to hide Shopper and Stock Remaining Counter on product pages you do not want it to appear on. This workaround is only feasible if you wish to hide Shopper and Stock Remaining Counter on a few product pages.
