This post is mostly a reminder for myself. I modded the current theme (iNove by mg12) so that the links on the link page are shown in categories.
In links.php I replaced:
<div class="boxcaption"><h3>Blogroll</h3></div> <div class="box linkcat"> <ul><?php wp_list_bookmarks('title_li=&categorize=0&orderby=rand'); ?></ul> <div class="fixed"></div> </div>
with:
<?php wp_list_bookmarks('category_before=&title_before=<div class="boxcaption"><h3>&title_after=</h3></div><div class="box linkcat">&category_after=<div class="fixed"></div></div>'); ?>
Ugly, but it works great
