This may be so basic that not described, but no results in Support or Codex for "category roll" at all, or in "updated category" that are relevant.
Is there a feature in 1.0 or 1.5 that rolls the category names, or is it necessary to create a links category with the links to each category duplicated and calling that link category instead of the blog's category list?
Do you want:
a.) A list of category links in the sidebar?
or,
b.) A separate page that features a list of category links?
a.) is what I was thinking about, and b.) is interesting, but had not thought about it yet, thanks.
Just add this to your sidebar:
<li><h2>Categories</h2>
<ul>
<?php wp_list_cats(); ?>
</ul>
</li>
