Shows YouTube™ Video descriptions in Gmail™.
When you enable notifications on YouTube, you have the ability to enable notifications by mail.
In the past, YouTube would add the description to those mails. However, since the Material redesign, they're removed the description.
This extension brings it back, while having performance in mind and it doesn't collect any user data.
The Code is Open-Source on GitHub: https://github.com/kurtextrem/Youtube-Description-For-Gmail
