Is there any opportunity to change Thunderbird Address book fromat from "Outlook"-like to more flexible one? How can people nowadays imagine that a person cannot have more than 2 email adressed and 1 (one!) mobile phone? What should I do, if I have a contact, say, with 3 emails and 3 mobile phones? Just in case, consider Apple Addressbok and Soocial.com. They support unlimited number of fields per contact, and right they are.
