Does he just mean the name of the template, or was he saying he wants to show the Filename that HFS is currently using. I have looked for this before when I had multiple copies of something and just a "Copy of %originalfile%" and I wasnt sure which files was being used, and some times screwed up my custom settings. Assuming thats what he meant, ignore this, if not, could this be added easily?
So it would be like: HTML Template - myfilename.tpl
