This is a WordPress plugin that helps visualize the position of action hooks in the front-end. It is compatible with any theme or plugin as long as it doesn’t use dynamic names for its actions. 
This plugin detects once per day all “do_action” (except dynamic ones) functions from .php files in the wp-content/plugins & wp-content/themes folder & highlights their position in the front-end of the website when requested. 
Only administrators will be able to see the highlights.

Visual Action Hooks

Detect action hooks added with "do_action" function from any theme or plugin & display them for logged in administrators.
