GD Rating System Pro is still in development. This is the third public Alpha version bringing many more changes and fixes with several more planned features completed, including new rating method: Stars Review.
GD Rating System Pro 1.0 Alpha #3 brings new rating method called Stars Review. This method allows only post authors to set a single rating for the post with the additional subject text and description. This is basically using stars for setting the review rating for the post by the author. Shortcodes and widgets needed for this rating method are also implemented. GEO Location features are now in own addon for easier control. Ratings and votes logs are updated and improved. WP Rest API support is completed as planned for the 1.0 version.
Next and very possible last, Alpha version will bring Thumbs Rating rating and rich snippets addon. It should be ready for released over the weekend.
