[ic] Multiple shipping addresses

[Interchange user]

Hello,

I'm having trouble making sense of multiple shipping addresses. All seems a 
little messy and confusing to me. ;-)

>From what I can see, shipping charges are not increased accordingly if 
someone uses multiple addresses per order, and the other problem is allowing 
people to type in their country when adding or editing an address, rather 
than selecting it from a drop-down list (I am calculating shipping by 
country).

I would prefer to simplify things anyway, and just have one shipping address 
per order. It would be good to support saved shipping addresses though, and 
have the customer select the required address on the checkout page (like 
Amazon).

Does anyone have any examples, or can someone point me to the relevant 
documentation? I couldn't find any reference to the [address], [modifier], 
mv_ip, mv_an, etc. tags / form variables from the 'cart' component.

Also, where is the code behind the ship_addresses.html page? I couldn't find 
any reference to the [table-editor] tag. What does the 'Save here only' 
checkbox do?

Thank you.
