Softhing, a developer of creative writing tools for Mac OS X, has updated Storyist, a story development tool for novelists and screenwriters, to version 2.2. The upgrade now runs in 64-bit mode in Mac OS X 10.6 ("Snow Leopard").

Version 2.2 also adds support for exporting to the ePub format and sharing with Stanza for the iPhone. Anyone with an iPhone, a local network, and the free Stanza for iPhone application can download manuscripts and screenplays from Storyist and read them on iPhone. What's more, Storyist now has new automated actions. New styled text actions convert paragraphs with leading tabs to first-line indents and back.

Storyist provides a word processor with the features writers expect from a top-notch writing program, including spelling and grammar checking and a page layout view with support for headers, footers, and style sheets. It also provides a number of features not found in typical word processing applications and screenplay formatters.

Storyist 2.2 is compatible with Mac OS X 10.4.11 and higher. The download-only version is $59 and a download + boxed set (CD + printed manual) version is $79. Both are available through the company’s online store (http://www.storyist.com/store).
