WordPress adds all kinds of <code><meta></code>-tags to the <code><head></code> section of your site. 
Some of these tags are quite good and have real uses, others make sense for some sites and others doesn’t. 
Some tags are even considered a security risk, since they tell the world which version of WordPress you’re currently running.
This plugin allows you to remove all of the <code><meta></code>-tags that WordPress outputs by default. 
You decide on a tag-by-tag basis which tags to remove and which to keep. Nothing’s enforced, you’re 100% in charge.

WP Hooks is a plugin for WordPress that allows you to add JavaScript, HTML, or other code to your 
header and footer without modifying your theme. WP Hooks uses the wp_head() and wp_footer() hooks 
built in to WordPress to add content to your header and/or footer. It’s great for those who have 
custom JavaScript, CSS, or other code (Google Analytics, meta tags, etc.) in their header or footer 
and don’t want to or can’t modify their theme.
