Order listing

Is there a way to show amount of items ordered with total amount of order? Is it possible to add amount of items to exported csv?

Hi,

1.
I didn't really understood your question, can you please explain it with more details ?

Sure, you'll just have to :
- Use the product export CSV function
- Edit the CSV and change the product_quantity column.

In the order listing, there is total sum of order. I have only one item in my shop, i'd like to have amount of ordered products next to total sum, is it possible?

Yes I think that you'll have to edit some file but can you explain it with for example screenshots of what you have and what you want ?
