Made this because I always forget that button exists. Supporting content creators is good :)
About
- This script checks the channel name below the video against the subscribed channel list in the guide (retractable sidebar) and clicks the like button if there is a match.
- A slight delay after loading the page is normal—the script has to wait for the guide to load.
- This script has no effect if you've already liked the video or you aren't logged in.
