App

Expected behavior

We're trying to establish coding conventions for our projects and use development/staging/production config names only.

shopify app link --config=my-name should skip the config file name question and create or update the shopify.app.my-name.toml file

Actual behavior

The app ignores the custom name parameter and shows a prompt with the app name as a pre-filled suggestion

Verbose output
