Functions in need

Thanks Open Cart Team first.
It would be best to add following function:
Shipping module( Prestashop has this function, but not perfect yet.)
---------To calculate DHL shipping cost exactly, there are three factors: the weight of products, the buyer's country(different country zone has different fee), whether the posting address a remote area.

Minimum order quantity module ( Little e-commerce system support this function)
----------Each product can have a moq number, default moq should be 1

Products Images
----------I found that if to upload a additional picture with a name already used by another product,after upload, in the picture folder, the old picture will be covered..That's harmful, not smart. It's better to define the uploaded name of picture in the image folder automatically.

Appreciate who can answer and solve these questions.

1. There are dozens of Shipping Modules. Have you even looked at the cart? DHL has a custom API that needs to be coded. I have some made for USPS, UPS, and soon FedEx here: http://www.unbannable.com/ocstore/shipping_modules But there are also default ones that come with OpenCart

2. This is being added in the next version I believe

3. If you can't manage a few pictures, then that too is "not smart". A file system on a web server is no different than it is on your own desktop. Tho perhaps case doesn't matter on linux, but i digress

Can us open cart fans know when will the new released version come?Many thanks for administrators.
