Chrome Webstore Extension Request

There is this really cool Chrome extension for SpigotMC where it'll send a notification when you get a new alert and will display a badge on the extension icon. Here is the SpigotMC extension: https://chrome.google.com/webstore/detail/spigot-notifier/dpkibifcklglomemgflhamcdohfobfpd

Was wondering if anyone could make an extension like that for Polymart.
