Regardless of your theme, JQuery Accordion Menu Widget turns your menus into hierarchical, collapsible widgets. Just drag any page, post, category or custom link into your menu; sort it into parents and children; and the Accordion Menu will present it in a compact, organized fashion, turning an unruly mess into a neat navigation. The free plugin comes with several skins (themes), and anyone with a basic knowledge of CSS can craft their own.
Link rot is inevitable. Content can get taken down or moved, URLs change or disappear. One of the most unfriendly first impressions a visitor to your site can have is the dreaded "404: File not found" error message.

The free Redirection plugin handles these situations and more. It can automatically monitor changing URLs and create a 301 redirect, which Web browsers and Google understand to mean the old content has a new home. Redirects can also be imported from an existing .htaccess or CSV file, and manually defined using regular expressions (regex), which can redirect countless content requests with just a single formula. Exhaustive logs detail every time one of these redirections is invoked.
A neat bonus feature: Redirection can create an RSS feed of your 404s. By monitoring this feed, webmasters can track what pages users are looking for and not finding, and can then create redirects for the most common requests. Have multiple sites? Create a Yahoo Pipe that combines all your Redirection 404 feeds into one easy-to-monitor feed.
WordPress stores wiki-like revisions of your posts, tracking every edit and storing each version as a separate entry in the database. This feature can cause database bloat and offers little in return if you don't refer to your revisions (or are doing your editing in a different tool entirely). You can edit the wp-config.php file to limit or disable revisions globally -- but sometimes you need more control than that.
