I love this plug-in but needed to create about 60 custom-type posts and it only supports Posts and Pages. I modified the code to support custom post types. It works! :)
I posted a message for Sarah@HowdyBlog with the new code and hopefully she will have a chance to review and integrate the changes soon. If you can't wait for that, contact me directly or just reply to this thread and I'll supply you with the modified code.
