The project is deprecated now since JI does not use its old course selection website any more.
It is a Chrome extension to simplify the button of UM-SJTU JI course-chosen website.
The original 'Course Selection' is very hard to use. I have to try several times to click it. Meanwhile, some icons are unnecessary.
Original icons
New icons with extension
If you do not want the source code, just download the release version is ok.
Go to Google Webstore (Blocked by you know who).
The source code is very ugly and I wrote it just because the website is really hard to use. If you are interested in it, please fork it and improve it.
