Key Features: 
* Shows current template file name 
* Displays template directory path 
* Click to view all included template files 
* Configurable display position (top-left, top-right, bottom-left, bottom-right) 
* Customizable background and text colors 
* Admin-only display option for security 
* Debug mode option (only shows when WP_DEBUG is enabled) 
* Lightweight and performance-optimized 
* Clean, modern interface
Perfect for:

Asset Queue Manager

Took ages to find this amazing plugin because of its odd title, and it was so helpful to finally find out what scripts were being loaded on each page. For example, woocommerce loads of lot of unnecessary scripts, so whatever plugins you are using, if your site is slow this plugin will magically help you find out what scripts you can dequeue.



Fantastic

I was just looking for a way to see what assets were loaded, to determine what plugins to desactivate on certain custom post type using Plugin Organize.
This plugin do that, but it can also do more, like let you show the source, the dependencies, the source link and even provide you a way to disable certain resources.
Maybe a simple list or assets would have been more readable than the actual GUI, but it is nice anyway :)
It is somehow close to what the Gonzales (not free) WordPress plugin has to offer, but Gonzales has a bit more rules to offer for de-queing the resources.
Anyway, this plugin is nice, and is a good complement to more complex plugins such as Plugin Organizer (for which you can define rules on post level).



Wo !

A tool for experienced frontend performance engineers to take control over the scripts and styles enqueued on their site.
