Has some OK features, but a lot of it can be done with just using the redirects built right into Shopify. The customer URL shortener doesn't allow you to have your domain and then text, it just created random numbers and letters. Not sure who wants to share mywebsite.com/rthr154 as opposed to mywebsite.com/greatproduct.
Thank you for your feedback! We have added the functionality in our app as you required, please check.
