Thank you Colin.
Refrreing the attached screenshot I still unable to find which layout shoudl work for me. No matter which layout I activate, has no effect on the link in the article whihc makes me think I am not at the right spot. I don;t see "Files link and icon v3.2" anywhere in my setup whihc default installation.
I also noticed the link you provided seems a bit outdated and has broken links.
