Not the worst attempt at coding; certainly not the best either. Addresses are not exported in any form. So! I guess we write them out by hand or memorize them. Awkward interface.

Hopefully the developer will READ THIS and issue an UPDATE SOON to offer a more functional and intuitive tool. Meanwhile keep looking. I should have.
