Codeforces Customizer is a Chrome extension designed to customize and extend the Codeforces platform, providing users with an enhanced experience. Developed by Manan Shah, this free extension falls under the category of Browsers, specifically Add-ons & Tools.

The extension offers several features aimed at improving the user's interaction with Codeforces. One notable feature is the Enhanced Blog View, which eliminates the need to scroll through all blogs. Instead, favorite blogs are hidden, reducing scrolling and allowing users to easily search for specific blog titles using a custom search bar. Additionally, users can expand or hide individual blogs to view their content, making blog navigation more convenient.

Another useful feature is the All Submissions tab, which allows users to directly access the status tab for the current problem from the problem page. This saves time and simplifies the process of reviewing all submissions related to a particular problem.

Furthermore, Codeforces Customizer includes the option to show results with user lists by default. This eliminates the need to manually select the user list in the problemset or contest page every time. By entering the list key in the extension's popup input box, users can ensure that the problemset or contest page automatically displays results using the specified list.

Overall, Codeforces Customizer is a valuable Chrome extension for Codeforces users who want to customize and enhance their experience on the platform. With features such as Enhanced Blog View, direct access to all submissions, and default user list results, this extension offers convenience and efficiency to users navigating Codeforces.
