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).

This is a simple tool that helps you provide the site verification code and file generator for any service that needs to verify the site 
via a comment / meta in the head section or via a file URL.
This is a generic site certification tool. 
To use it, just add the plug-in and turn it on as needed. 
You will no longer need to FTP a file to the site root or add extra tags to the header.php in the template to enable your site to be verified by third-party services.
Some examples: 
Google webmaster tool needs a file called googleXXXXXXXXXXXXX.html with no contents. 
OR 
<meta name=”google-site-verification” content=”XXXXXXXXXXXXXXXXXXXXXXXXXXXXX” /> in the HTML head, 
Without this plugin, you would have to create a file and FTP it to your server or edit your template. With the plugin, you can generate the verification method needed automatically via the control panel.
Similarly, Trustwave SSL wants a file called cert.html with the contents of 
“Trustwave SSL Validation Page”

WP Site Verification tool

A tool to enable verification of site ownership via file or meta tag.
