This plugin sorts the items in the “Settings” and “Tools” dashboard menus in alphabetical order. Useful when you have lots of plugins installed and very cluttered menus as a result. The plugin should work well with most “drop-down menu” plugins and other visual enhancements.
You can configure which menus are sorted by editing the source code. Yes, hackety-hack 🙂
