First versions of Absolute Comments implemented several features that are now, out of the box, part of WordPress.
Absolute Comments now simply adds a “Reply” link into comment notification emails, prefills the comment reply with the commenter’s name, and adds a few cute icons.
There’s no option or settings: just activate and forget it’s even a plugin.

Lets the admin add “featured” or “buried” css class to selected bbPress replies. Handy to highlight notable replies or bury “Thanks/me too” and other useless responses. The plugin also gives the user that started the topic the capability to choose featured/buried replies. Also includes a widget for showing recently featured replies.
This plugin is based on <a href="https://wordpress.org/plugins/feature-comments/" rel="ugc">Featured Comments</a> by Pippin Williamson.
