That would absolutely work. It sounds easy and it doesn't take up any screen real estate.
I too think this would be nice. When connecting via domain name, showing the IP address will let me know if I have connected via IPv4 or IPv6 (without having to consult a log file)
Thanks for your suggestion.
We will see, if more people ask for this.
Is it possible to have the IP address in the top bar along with the hostname as an option?
Sometimes it can be difficult to see what's going on, obviously you can have the IP in the name but handy to have it as an ON/OFF option.
