The Tab Override WordPress plugin was updated to version 3.0 today. This is an almost complete rewrite of the plugin and includes several new features, notably:

• a new auto indent feature
• translation support
• the addition of tab_override_init and tab_override_add_scripts hooks

In addition, there are enhancements to both security and performance as well as a new uninstall procedure and much improved documentation. Most of the code was refactored into a class. Since some PHP 5 features were utilized, PHP 4 is no longer supported. This version of the plugin also includes support for the upcoming WordPress 3.2 release and the fullscreen editor mode.
