No testimonial rotation in widget
No limit on words / character - all or nothing
No excerpt support
No pagination on shortcode pages
Lack of features render this plugin virtually useless - I can't think of any way to implement it effectively out of the box on a modern website.
Suspect all the super enthusiastic ratings are from people who have either never used a wordpress plug in before and are happy with "hello world" or work for the developer.
If no stars was an option that's what I'd give it. Really disappointing - don't waste your time like I did!
