Hi, thanks for implementing this feature.
I have been playing around with the Metadata plugboards to get the titles on a Kindle 3 to show series information. I used the following template:

{series} - {series_index:0>2s} - {title}

With title as the destination field. This works very nicely for books that are part of a series e.g.:

A Song of Ice & Fire - 01 - A Game of Thrones
A Song of Ice & Fire - 02 - A Clash of Kings
A Song of Ice & Fire - 03 - A Storm of Swords
A Song of Ice & Fire - 04 - A Feast for Crows

Is what shows up in the title field on the Kindle.
However, when a book is sent that is not part of a series, I get a leading - - in the title e.g.:

- - To Kill a Mockingbird

I am wondering if there is a way to eliminate the extraneous dashes at the start of the title when there is nothing in the series field. Or alternatively, an easy way to turn the plugboard on and off depending on whether the book being sent is part of a series or not.
