Lists WordPress require() calls mainly for plugin code refactoring
This plugin dumps the colorized filenames and filesizes after the normal WordPress output, after the closing html tag. This generates invalid HTML but gives you an overview of plugins and the current theme.
This plugin lists all files parsed and executed by the PHP engine. It can be used for plugin or theme refactoring.
Please watch this WP core bug to get more information about WordPress entry points.
