A Chrome extension to notify the result of the submission on AtCoder
This extension shows a desktop notification with a sound about the judge of submissions that are waiting for judge or judging when the submission page https://atcoder.jp/contests/****/submissions/me was opened.
The notification won't be shown if the tab or its window is active.
The tab will be active by clicking the notification.
You can disable the notification, and you can also disable the sound from the menu that appears by clicking the extension
