Polygon Recent Comments With Avatar


A new updated version of mine is aimed at expanding features related to discussions and authors on the blog. In this version, new features will be updated and requests from the user community will be accepted. The plugin is currently under review by the WordPress support team, and we will announce as soon as it is approved for release.



Some of the changes are as follows:




Rename the plugin Polygon Recent Comments With Avatar to Poly Comments to better align with the integrated advanced features.



Change the entire structure of the plugin.



Add the shortcode [poly_recent_comments] to display comments within post content, widgets, etc.



Poly Comments

Polygon Recent Comments With Avatar: Recent comments with avatar support, including Gravatar, date, username, user link, and scrollbar.
