I was using Trello before this, but there were always things for which I had to go back into Shopify, like fulfilling an order or updating a shipping address. With this app, I can do all of this without having to open Shopify.
Honestly I'm blown away. The app is a 10x improvement over the regular Shopify orders list, and even better than Trello or AirTable, because it's tightly integrated with Shopify. Whatever you do in the app also shows up on Shopify, so you have a single place where you can manage everything.
