Dredging up an old thread here, since it's the only applicable post that my search found...

Is there some documentation somewhere about what the accepted format strings are? I never would have guessed {tracknr:2}, for example.

edit -- okay, I found the list of field names by clicking the jEmplode link at the top. I still don't see where the :2 comes into play.

Specifically, I'd like to name tracks with a _ in place of a space. Possible? Or do I break out perl?
