I just uploaded the version 1.5 beta of MailTemplate for both Mail and Entourage.

This release includes the following changes:

• Compiled as a Universal Binary for both PPC and Intel
• Added support for Shortcuts by Abracode
• Added ability to use a template when selecting file in Finder
• Added real toolbar interface
• Added Command-Delete for Delete command in TemplateEditor
• Changed layout of TempateEditor
• Changed to Apple installer
• Disabled folder selection in Finder to work around long delays and potential issues

Enjoy.
