Page-Cat-List is a WordPress Plugin (surprise) that you can use for generating a sorted list (where you can/must 
define the order) with items from pages and categories. That’s the whole story. Unfortunately WordPress does not 
implement this in its core-functionality so I had to build that on my own.
As of writing this Page-Cat-List supports:
<ul>
<li>mix category- and page-items and display them in one list</li>
<li>sort these items (first level only)</li>
<li>define a title</li>
<li>define a maximum depth</li>
<li>define a html-id for the first ul-element</li>
<li>most of the stuff you can do with get_pages and get_categories arguments:
<ul>
<li>exclude items</li>
<li>include items</li>
<li>etc. pp.</li>
</ul>
</li>
</ul>

Page-Cat-List

Integrates a widget that displays category and page-items in one html list with support for a user-defined order.

Adds categories and tags functionality for your pages.
This plugin addsthe ‘post_tag’ and the ‘category’ taxonomies, which are the names of the existing taxonomies used for tags and categories the Post type ‘page’.
This enables the categories metabox and the tags metabox in the New or Edit Page interface.
The plugin has no settings, does not alter the database and only uses hooks to 
achieve it’s goal. It works perfectly fine with Multisite installations.
This plugin WILL NOT add any display of categories or tags to your template files.
