The Addressbook
StickyNote provides an address book in which you can store your friends' computer addresses with their names and comments associated.
The address book appears in a number of places. Perhaps most notably it autocompletes your text in the "Send to computer" dialog box. You will also notice the address book in your profile dialogs, the main menu, and other places.
When you open the Address book, you will be able to view all your contacts, edit their data, and delete them, with the appropriate buttons.
