Here you can choose different settings for the plugin - working principle (JavaScript, jQuery), the use of CSS, the number of comments and the like will be displayed recording element (avatars, alignment of text). Settings really enough for any occasions. In order to change something in the last block comments to the customer need only tweak these options.
To display recent comments in the blog there are 2 options. Firstly, you can go to sidebar.php template file and deploy a special code.
The second way is to add a special widget on the appropriate page. It is called WP-RecentComments with different parameters. All the main display element specified in the settings.
Generally WP-RecentComments plugin with recent comments widget - a very cool thing. This is a very comfortable, very easy and affordable, personally you would put him in the future on all developed custom blogs in Woocommerces themes.
