This plugin will help you categorize the comments on your blog posts.
If you are a food blogger, this plugin is very handy to sort the comments on your recipes, like, for example in “I have made this” and “I have not cooked this”.
You can configure the list of categories from the Settings->Comments Categories page. 
Besides the categories’ list, you can also customize basic look and feel of the comment filtering buttons.
In case the plugin is not working with your theme, please check the FAQ section for more info.
