Is it possible to somehow add a couple of functions?

Question

Google Chrome

Hello everyone, I have been sitting on another browser based on chrome for a long time, but due to a number of reasons I will have to leave it.
So the question is, is it possible to somehow do 3 things locally for yourself in chrome.
1. switch between open tabs simply by hovering over their area, that is, without the need for a click.
2. close the tab by right click on the tab area.
3. restore a graying closed tab with a key combination.
Thanks in advance for your replies.

Answer 1

Found an option, extensions for chrome AutoControl.
Performs more than it was necessary :)
I corrected a couple of new points for myself.
