Attach WC order number to invoice

Hi,

I just wanted to hear with you if you had considered adding the WC order number to the invoice? I suppose you can with some php, ie. ->get_order_number(); – but I’m a far way from doing that kind of php customization by my self ??

I think it would be a nice addition to an already great plugin.

Thanks!
