That's a great idea that would be helpful for many people.
I have just taken a look at the extra requirements here: http://dev.splunk.com/view/app-cert/SP-CAAAE85 and it seems like a file viewer and btool only version would probably be acceptable.
This will probably not take long to make so I will add it to my backlog. I think I will probably be complete in about 2-4 weeks.
Thanks for the suggestion.
