4BIS Innovations B.V.

Adds a shortcode that you can add after every list or chart item. The shortcode adds a block that lets you easily 
navigate between the previous and the next item. Integratable with google tag manager which allows you to track not only how many 
visitors on one page but how many visitors have clicked and read one paragraph. And each number has its own URL so when 
you share the url you instantly go to the right paragraph.

A simple address book plugin.
You can view and edit addresses (names, addresses, phone numbers, email addresses, etc.) in the administration interface (under Manage > Addressbook or as its own top-level menu item), or embed a read-only list of addresses in posts and/or pages.
Addressbook features:
<ul>
<li>Gravatar support for both address lists;</li>
<li>hCard microformat support in the address list.</li>
</ul>
Still to come (hassle me if you want these now):
<ul>
<li>Import/export to a bunch of formats;</li>
<li>Firefox Operator addon scripts to export external addressed into Addressbook;</li>
<li>Pass various options to the <code><addressbook /></code> element, to sort and limit and whatnot;</li>
<li>Templates for the address list display;</li>
<li>Photo upload (probably over-ride the Gravatar, and show a note that there is a Gravatar?);</li>
<li>Custom fields;</li>
</ul>

Addressbook
