I Hate GitHub White Space is a free Chrome extension developed by Hunter Ham Digital. It aims to improve the code reviewing workflow on GitHub by automatically adding the hide white space filter to the GitHub diff view. This extension addresses the issue of GitHub's website not providing a way to persist the "hide white space" setting in the code diff view, which can slow down the reviewing process.

The extension applies the hide white space filter to both Pull Request file diffs pages and Commit diffs pages. It detects if the white space setting is toggled by checking for the `w` parameter in the URL query/search parameters. If the `w` parameter is not set, the extension automatically adds `w=1` to the URL to hide white space. However, if users intentionally want to show white space, they can set `w=0` in the URL.

What sets this extension apart is its focus on security. It utilizes Chrome content scripts, which only run in the context of one tab/page, and is limited to the secure HTTPS protocol on github.com. This ensures a more secure browsing experience for users.
