SNU CRS Refresher is a useful add-on for students at Seoul National University (SNU) who are using the university's course registration website. This add-on is designed to disable the course registration program when it is already in use.

With SNU CRS Refresher, students no longer have to worry about accidentally double-booking a course or encountering any issues due to the course registration program being active. This add-on provides a simple solution by automatically disabling the program if it is already running.

It's important to note that the developer, Donghoon Shin, is not responsible for any legal consequences if the add-on is used in situations where it is not permitted by the university. Users should ensure they are using the add-on in accordance with the university's policies and guidelines.
