Dear Sir or Madame,

I have a customer who want's an online printstore but the store needs a product designer tool like the one your provide. I did take a look on the backend demo but unfortunately there are some features missing which the customer does need, especially this ones:

1.) Charge for each customization:
Let's say the customer adds text using the product designer, charge 5 Dollar, customer adds a picture, charge for it 10 Dollar and so on.

2.)Products with only specific fonts allowed. Lets say Product 1: Every font family allowed but on product 2: only arial and helvetica

3.) A text field on a specific position but images can be anywhere at product and other texts.
Actually that's all what would be missing and what does hold us on to buy your script. Is there any possibilty to add this features?
