Show HN: GitHub "Lines Viewed" extension to keep you sane reviewing long AI PRs (chromewebstore.google.com)

A new GitHub extension, "Lines Viewed," has been released to enhance the experience of reviewing lengthy pull requests (PRs) in AI development. This tool introduces a discreet indicator that tracks and displays the number of lines a user has viewed, complementing the existing "files viewed" metric in the GitHub PR interface. This functionality aims to help developers maintain their focus and organization during exhaustive PR reviews, which are increasingly common in AI projects that often involve extensive code changes. The significance of this extension lies in its tailored support for the AI/ML community, where code reviews can be particularly challenging due to the complexity and volume of changes associated with machine learning models. By providing a clear metric of engagement with a PR, developers can better manage their review processes, reduce fatigue, and improve overall collaboration efficiency. With a simple setup of just 12.17 KiB, the extension is designed to be lightweight and unobtrusive, ensuring that it integrates seamlessly into the existing GitHub workflow without compromising data privacy.
