The selection of available templates in the GAOTD download is really poor in quantity and variety. I understand you wish to sell additional templates however if I had just purchased Wondershare for $30 I would be very disappointed to find that I had to turn right around and purchase templates. Please don't get me wrong, I am very satisfied with Wondershare but I am not a template sort of user. I think most of your potential customers are and this could be an issue for them.
I routinely recommend GAOTD downloads to friends in several forums, my blog and on my website. Though Wondershare has lots of pros to mention this is a con that would also bear mentioning if I were reviewing it. Again, please understand that I really like the software package as a whole and could care less about templates myself.
