With ThemePark, you can:

• Create guiKits for use with Unsanity's ShapeShifter;
• Create new themes or icon sets using your own graphics;
• Merge your theme with an existing one to use it as a base or to make small tweaks to someone else's theme;
• Quickly preview your theme while you're constructing it;
• Easily find the element you're looking for using ThemePark's smart organization, filtering, and inline hints;
• Save in-progress themes and easily see which areas you've already modified;
• Edit resource files found inside of many applications;

• Added transparent support for 10.6's modifications to the SArtFile.bin format. 10.5 files will be automatically converted and you can save to either format.
• Added tagged copy/paste so you can copy arbitrary images one from one file and paste them into another without the element selection or the image sizes being identical.
• Changes made to Extras.rsrc will now actually stick when you apply the theme.
• Resolved an issue that could prevent a portion of an image from being editable.
• Resolved an issue that caused scaled images to appear distorted. There's still more work to do here, though.
• Resolved many issues that could arise when changing the size of an image.
