A few things to note:
1. you can add an extra field for each contact you create - making it very useful to specify something like an invoice number for your billing contact.
2. you can include a prefix for each contact - meaning that you can send emails to the same address but visually identify in the subject line as to which option was selected.
3. contacts can be displayed for either registered or guests.
I will work on ensuring this has a width control in future - keep an eye out here
