It should finally be possible to create several returns within one order. Currently you can only create one return. That is far too less.

On the other hand, the return items should be automatically added back to the stock. Currently you still have to do this manually. However, if an order is placed for this return item in the meantime, there are immediate stock inconsistencies.

Creating a credit note via a return is far too complicated for this. The creation of credit notes should be urgently improved.
