Some gaps Vdesigner

Sincerely expect your changes because even if you do not make us miss you since the plugin in this way has little use and more compromises the customer's purchase. I believe that until the next modification is not up will enable the Vdesigner.
However very disappointed in this release.

I tried to place an order with the configurator and I have two questions arise spontaneously.
The first is the final format that is a png and yet in my opinion should be a pdf, as if the user uploads an image file taken from the internet what I am in the ftp folder? a small file and then later I will have problems with the print quality.

The second is much more spontaneous, once the file is created with the configurator by pressing and save the configurator closes leaving as preview the original product, just click on add to cart see the created image. But if I was not an experienced user? how do I know that I need to click add to cart to see the preview?
Is not it better that once pressed saves the preview prendessei the place of the image of the product?

The component is functional but well-known loopholes that could facilitate the non-purchase by the customer.

I look forward to.
