Hikari Titled Comments enables each comment to have a title, so that commentators can give a subject meaning to their comments.

A normal comment without a title
One of the best features Drupal has and I miss in WordPress is the possibility to set title to comments.
With a title, we can identify the comment subject, it can be resumed to a phrase. Comments become more similar to articles and aggregate more value.
I like to see comments as mini-articles. The post being the main article and comments being mini-articles that extend the main one. Now with title, WordPress comments are a bit closer to that approach.
Hikari Titled Comments enables each comment to have a title, so that commentators can give a subject meaning to their comments.
Features
- Comments titles are stored as comment metadata.
 - It’s easy for themes to add support the plugin, being the support optional and when the plugin is not available the support just remains hidden.
 - A simple function prints the comment title if there is one, or prints nothing if current comment doesn’t have a title.
 - Comments titles can be edited from admin comment edit page.
