Toggle Heading is a Chrome add-on developed by zhaipengchao367. This free tool is designed to make headings of a web page collapsed, providing an organized structure for articles, papers, and documents. It is particularly useful when reading content with a clear hierarchy.

The add-on allows users to collapse headings, making it easier to navigate through long and complex articles. By collapsing headings, users can focus on specific sections of the content without being overwhelmed by the entire page. However, it is worth noting that the add-on may not work well on every website due to variations in web structures.

For those interested in customizing the add-on to suit their needs, the source code is publicly available on GitHub. Users can access the code and make slight modifications to ensure compatibility with the websites they want to read. Toggle Heading offers a convenient way to enhance the reading experience for those who prefer a structured approach to consuming online content.
