The default Recent Comments widget in WordPress is shockingly incomplete; luckily, Krischan Jodies spent his personal time to build a proper Recent Comments widget. Once activated, you will need to visit Appearance | Widgets. A new Recent Comments widget will be available to drag to your sidebar. Out of the box, the plugin needs no configuration, but Krischan provided a very comprehensive configuration engine that can be accessed through Settings | Recent Comments.

The plugin, Recent Comments, also comes with a Recent Trackback widget. You might ask "What's a Trackback?"; a Trackback is simply when someone mentions your post or website on their blog or website.
