Hi,
We really need it!
And you will have it
Nicolas finished the implementation and he still need to do some tests because the order/order_product algorithms around the modification of the product quantity changed a lot.
The main goal of HikaShop 3 was to refactor some important parts in the code, during the last year (and a half), a huge part of the HikaShop core has been rewrote.
Some elements already been included in HikaShop 2.x but for the parts which could break the compatibility, we preferred to wait for that major release.
Regards,
