sugang_timer is a Chrome extension developed by yeomyeom that provides a convenient way to automatically refresh web pages at specific times. This extension is particularly useful for online registration and ticketing, where accessing the page at the exact time can greatly impact success.

The usage of sugang_timer is simple and straightforward. Once you are on the desired web page, whether it's for course registration or concert ticketing, you can set the desired time and click the start button. At the specified time, the page will automatically refresh, ensuring that you have the best chance of securing your spot or tickets.

It's important to note that the timer must be visible on the screen for the refresh to occur. Therefore, it is recommended to avoid any interactions when the countdown is less than 10 seconds to ensure a smooth experience.
