Here’s a short list of plugins I find incredibly helpful to maintaining my Wordpress sites:
The lazy and the productive will love it : all admin links available in a neat CSS driven drop down menu. No need to click on “Manage” then “Pages” to edit pages, go to any admin page from any admin page.
As a whole, the new WordPress Admin panel is organized fairly well, however when it comes to editing posts or pages quickly without having to open each post or page in a new tab or window, it isn’t a very efficient process. For those who are using WordPress as a CMS, it’s important to be able to manage contents easily and quickly. That’s what this plugin helps to do.
It adds some icons to the posts/pages management panel with AJAX-driven CMS-known functions like toggling post/page visibility, changing publication date and title without having to open the edit screens or reload the page, plus changing page order with drag’n'drop, inline category management and inline tag management, plus much more.
Audio Player provides you with a simple way of inserting a stylish Flash mp3 player on your WordPress posts and pages.
Features include configurable colour scheme, enclosure integration, runtime options such as autostart and loop and ID3 tag integration.
WP Easy Uploader was created to make the life of WordPress bloggers easier by allowing an Administrator to add plugins, themes, and any type of file to WordPress directly from inside WordPress. You no longer have to load up an FTP client just to try out that latest plugin or to upload a text document for people to download.
Yet Another Related Posts Plugin (YARPP) gives you a list of posts and/or pages related to the current entry, introducing the reader to other relevant content on your site.
This plugin adds a checkbox, “include this page in menus”, which is checked by default. If you uncheck it, the page will not appear in any listings of pages (which includes, and is usually limited to, your page navigation menus).
