After I started opening remote files with Tramp, I wanted a quick way to tell which host the file I was editing belonged to. I found someone who had written a useful article, so I tried applying the same setting to my Emacs.
Configuration
I used the settings described on this page. Much appreciated.
Show the time and file name in the Emacs title bar
With settings like this, the full path of the file is displayed in the title bar. The time is shown too.
For files opened remotely, the path includes the host name, so this works well with Tramp.

Thanks for the excellent information. This made Tramp even more convenient to use.
