Lists WordPress require() calls mainly for plugin code refactoring
This plugin dumps the colorized filenames and memory consumptions or filesizes after the normal WordPress HTML output, after the closing html tag. This generates invalid HTML but gives you an overview of loaded plugins and the current theme.
What's running lists all files parsed and executed by the PHP engine. It can be used for plugin or theme refactoring.
Provide a part of its path in wp-config.php:
define( 'WHATS_RUNNING_HIGHLIGHT', 'wp-content/plugins/my-plugin' );
You can find some documentaion here what makes a WordPress plugin efficient: https://github.com/szepeviktor/WPHW
