GD SEO Toolbox Pro 2.2 is a new update that brings many improvements and several fixes related to metadata processing. Major new feature is preview tab for the post, the term, and the user meta boxes.
Metabox on post edit, term edit, and user edit screen is expanded with additional tab for a preview of all elements that will be generated for posts, terms and users. You can see the example of such preview on the image below. If the data entry is required but missing, it will be marked in red color. If optional data entry is missing, it will be marked in purple. Green entries are valid.
Facebook and Twitter modules got many improvements for building data, and also options to use user gravatar image for the author archive image. Metabox has improved styling (including responsive support).
There are numerous fixes for Meta Data addon related to saving the rules and handling some specific situations. Also, there are few fixes related to Facebook and Twitter and problems with fallback information use.
If you notice any problems with the plugin, stop by the support forums to report it. Let me know what you think about the new version, and as always, suggestions are welcome.
