http://sixrevisions.com/tools-of-the-trade/helpful_wordpress_plugins_advanced_users/
"This article presents 15 WordPress plugins to help enhance and simplify the blogging experience of advanced users, especially web developers and designers. Most of the plugins were tested on a default installation of WordPress version 2.3.1 for basic functionality; relevant screenshots of the plugins in action are included.

What’s a savvy user?

1. A blogger with basic to expert knowledge of HTML/CSS, and for a lot of the plugins featured here, PHP and MySQL experience is highly recommended.
2. A blogger who needs to display complex content in posts and pages like displaying and colorizing code snipplets, running custom scripts only on certain posts or pages, incorporating custom web forms, etc.
3. A blogger who knows what they’re doing - The default configuration of WordPress is too "fool-proof". For example, with the visual editor turned on, it will add unexpected indents and line breaks even inside

    tags. Additionally, it blocks you from adding 
    tags, automatically "sanitizing"  them into 
    tags.

If you match any of the above criteria, read on and maybe you’ll find a plugin or two that will make your blogging experience more convenient."
