Objectpark Development today released LetterWorks 1.1, the latest version of its Mac OS X application for writing “quality letters with ease and style.” LetterWorks allows users to create professional quality letters by facilitating PDF letterheads that print with your letters, choose from the stationeries included, or roll their own using the built-in layout editor, fill in the receiver’s address instantly via drag & drop (supporting the Apple Address Book), and use all popular word processing features, plus advanced features like kerning adjustment or rotated text. Version 1.1 includes several improvements and bug fixes and requires Mac OS X 10.2 (Jaguar) or later. LetterWorks is priced at US$29.95.
