This release adds a user-requested feature as well as some minor enhancements, bug fixes and other miscellaneous improvements. A user asked me to add a way to easily figure out what the post ID was so they could specify it when using the shortcode. While there are ways to do that already, they mostly involve looking at URLs and trying to pick out the right numbers. I decided to add another metabox to the testimonial creation screen that will output the shortcode plus the correct ID for that testimonial.
