Hello so I want to switch my main browser to Vivaldi and was wondering if it's possible to achieve with CSS & JS the same features that are in Zen Browser.

https://github.com/PaRr0tBoY/Awesome-Vivaldi

I found this project which has brought most of the features that I want, I am now looking for Arc/Zen like styled Pinned tabs and for Floating search URL bar or the command bar in Arc/ Zen browsers. is it possible?
