I asked the same question and was told by another forum poster that it's GONE.

it's all a bit odd because you can still use the feature in TURBO LISTER but then it disappears once your listing goes live on Ebay.

Very frustrating because it was once of the best features in TURBO

I doubt if many folk used it as there were a limited number of options and most sellers don't want their listings to look like everone elde's and there are so many free templates and template designers available if you google for them.
