This plugin allows you to get better control on how your categories are listed. It provides a widget which lets you get more options than the default WordPress category widget (show RSS, hide empty categories, etc.). Furthermore, it allows to hide the children categories and use clickable buttons to expand them. The plugin requires jQuery to be included in your theme. It degrades nicely when javascript is not available to the usual WordPress category list.
All the instructions for installation, the support forums, a FAQ, etc. can be found on the <a href="http://enhanced-categories.vincentprat.info" rel="nofollow ugc">plugin home page</a>.

Enhanced Categories

A plugin for wordpress which allows you to list your categories in a sexier way. Very useful when you have a great number of categories.

This will give you an advanced pagination to distribute your link-juice more evenly across your paginated paged. It also provides a better choice of navigation to the user to explore and find your content.
You can turn the pagination on/off separately for:
<ul>
<li>homepage</li>
<li>search results</li>
<li>category archives</li>
<li>date archives</li>
<li>tag archives</li>
<li>author archives</li>
</ul>
Or implement it directly into your theme using <code><?php the_wp_lopa('pages_below'); ?></code>.
You can also choose if you want it to be displayed before and/or after the loop content.
The plugin is currently available in English and German. If you want to help translate it, just write me an email. Help is much appreciated!
