Ash here from the Shopify team.
Thank you so much for your feedback on the Apps section of the admin. I definitely appreciate where you're coming from with this feature suggestion. While we currently don't have a way to categorize or sort installed apps in the Shopify admin, I am happy to bring this suggestion to our developers and express the benefit this would have on your workflow. We can't guarantee that feature suggestions will be implemented, but the more we see a feature being requested, the more likely we are to see that feature added in a future platform update. Making commerce better for everyone is one of Shopify's goals, and so user feedback is extremely important to us.
Please feel free to let us know of any other suggestions you have!
