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.
<a href="http://hikari.ws/titled-comments/" rel="nofollow ugc">Hikari Titled Comments</a> enables each comment to have a title, so that commentators can give a subject meaning to their comments.
<h4>Features</h4>
<ul>
<li>Comments titles are stored as comment metadata.</li>
<li>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.</li>
<li>A simple function prints the comment title if there is one, or prints nothing if current comment doesn’t have a title.</li>
<li>Comments titles can be edited from admin comment edit page.</li>
</ul>
I dedicate Hikari Titled Comments to Chiih-chan, my kawaii great frient ^-^
