BlackSheep is an AddressBook. But not a normal one. Have you ever tried to add 5 Phone-Numbers or 6 Potals?! If yes, this is for you!

BlackSheep is able to store as much Postals, Phonenumbers or every other information for a Person as you want. There are no limitations.

The next important thing is the searchbar. You only enter a few chars and the list only shows all addresses that match this search String. Like the Mail Searchbar in Mozilla Mail.

Just try it for yourself or look at the screenshots.
