Extension that creates a timetable of your WebReg classes and shows you where the class you are hovering over would fit in your schedule. This uses timetable.js. It also allows you to quickly generate a google maps route of your classes.
The code is pretty jank, but if you want to fix that make a PR :)
If you use Google chrome, Opera, Brave, Microsoft edge, or most other chromium based browsers you are likely able to just install the extension from google's web store: https://chrome.google.com/webstore/detail/ucsd-schedule-visualizer/jkaheldanccinoefddienccoblmcmhgn/related?hl=en&authuser=0
How to install manually:
Press "Load unpacked extension" and then select the folder you downloaded from this page.
The steps may vary depending on the browser used. You can always look up "How to install unpacked extension in [Your browser name]?" and you are likely to find a detailed explanation.
