How to go back to the old People Switcher interface of Chrome

Are you missing this People Switching icon?

With the latest update (Jan 14, 2015), Chrome forces us to use the new interface for People Switching as following:

and this is really annoying, way more complicated than the old one. People's yelling at each other asking how to reverse the update...blah blah blah...

Here you go, there is a Chrome's setting (advanced users) to turn that new interface off:

1. Go to chrome://flags/#enable-new-avatar-menu

2. In the "Enable the new avatar menu Mac, Windows, Linux" setting, choose Disable.

3. Click "Relaunch"

and the world is happy now!
