I would like to see more of the information about a web site and what protocol and security it is using. Similar to the way it was displayed in IE.
When you click on the lock next to the URL in the address bar in both old Edge and the new Edge, the information is rather lacking. In IE, I could go to File --> Properties and get very detailed information about many, including the version of TLS that is being user, what the doctype is, and what protocol was used.
While this may not be something every user needs, I think some advanced users and systems admins would and do find it useful when troubleshooting user issues. NOTE: This was and is a pet peeve of mine in the old Edge browser as well.
Very limited information...Far more useful and helpful information.
