Steps to reproduce the problem:
Dear all, 

I would like to suggest a new feature by that a small visual notification is being displayed when switching tabs using Alt + Number Key.

What is the expected behavior?

What went wrong?
This would essentially help the user to quickly navigate to the right tab knowing the correct number of the tab.

I further described this request in the following screencast:

What is your opinion on this request?

Thankfully,
