Fist of all; great piece of software!
Then I have questions/suggestions:)
1. As result of order status change user receive information that status of has been changed. Link '...user/order?order_id=xx' leads the user to the site form where user has order items and... the link 'download invoice'.
Problem is that this is too early phase to send customer an invoice. If customer cancel order or will not pay (abandon) shop will stay with order what means tax consequence (I cannot simply forget or delete it... I must correct it according to the law). So, is it possible to define when customer see this link and can download invoice. Some kind of option:
'customer can download invoice when order is: Pending ConfirmedCancelledRefunded...'
Practically for us this link has sense only when order is 'Shipped', 'Paid' or 'complete' but maybe some other users will want to decide in other way.
2. Discounts. In configuration-->Other config there is an option 'Product price qty discount'.
I really do not understand what I should put in to make it work. What I would like to achieve is that customer has 10% discount if for instance order value reaches '1000'. What I should configure (maybe not only this field?) to make it works?
