Storyist includes support for a number of Leopard features.
Grammar Checking
Using the new built-in English language grammar checker, you can catch "itsos" and other common grammatical errors before your editor does.
Smart Quotes & Friends
Storyist can now automatically substitute curly ("smart") quotes for straight ones, recognize and convert links as you type them, and preserve the proper spacing around text you copy or paste.
Picture Editing
Using the new picture taker, you can select, zoom, crop, and add effects to your photos by clicking on a picture in a story sheet.
Project Pane and Outliner Enhancements
When running on Leopard, the Project pane and Outliner provide improved visual feedback for drag operations and the ability to select an outline item by typing the first few characters of the item's name.
