AtCoder VirtualContest-Connect is a free Chrome add-on developed by kiruto398 that aims to enhance the experience of participating in virtual contests. This unofficial extension allows users to simulate a connection to the actual contest, providing real-time information about scores, rankings, and performance.

With AtCoder VirtualContest-Connect, users can view their current score and see how it would rank in the actual contest. Additionally, the extension displays the final ranking and performance of the virtual contest scores, with an option to hide this information if desired. Users can also toggle between displaying the information for rated participants only or for all participants. The extension even includes a tweet button for sharing the final results.

In addition to the functionality on the virtual contest ranking page, AtCoder VirtualContest-Connect provides a popup window accessible through the browser's extension icon. This popup displays not only the virtual contest ranking information but also the remaining time, score, and time elapsed.

For easier social sharing, the extension includes a tweet button on the virtual participation page.

Please note that AtCoder VirtualContest-Connect is an unofficial extension, and users are advised to use it at their own risk.
