The post is about a community member trying to remove a background warning while testing with the browser's inspect tool. The comments discuss the possibility of allowing the use of the browser's device preview mode within the builder, which the community members consider a valid use case. They suggest subscribing to a related issue on GitHub and plan to implement this feature. The comments also mention adding more device selection options, including custom naming, and removing the alert in the preview mode. Some community members suggest additional features like the ability to move the body around and switch the UI to something similar to Figma.
