#### The Long Version ####

The point of this plugin is to wisely minify HTML without doing "stupid" (unstable) minify methods like bundling external resources and forcing them to load in some messy new file name which is pointless after HTTP/2 anyways.

The minification only happens in the front side, avoiding these contexts:

- Admin area
- During WP installing process
- WP CRON requests
- XMLRPC requests
- WP CLI commands
- Login / register / forgot password pages

I have added some constants, and all constants have boolean true|false data types, e.g:
define('MINIFY_HTML_REMOVE_EXTRA_SPACING', false);

This is the complete list of constants the plugin manages:

MINIFY_HTML
Enables the plugin functionality
Enabled by default

MINIFY_HTML_UTF8_SUPPORT
UTF8 support for regular expression operations
Enabled by default

MINIFY_HTML_REMOVE_LINE_BREAKS
Removes line breaks in HTML (except in styles, javascript code, and the content of textarea and pre tags)
Enabled by default

MINIFY_HTML_REMOVE_COMMENTS

#### Compatibility ####

This plugin has been designed for use on LEMP (Nginx) web servers with PHP 7.0 and MySQL 5.7 to achieve best performance. All of our plugins are meant for single site WordPress installations only; for both performance and security reasons, we highly recommend against using WordPress Multisite for the vast majority of projects.

Note: Any WordPress plugin may also be loaded as "Must-Use" by using the [Autoloader](https://github.com/littlebizzy/autoloader) script within the `mu-plugins` directory.

#### Defined Constants ####

* `define('DISABLE_NAG_NOTICES', true);`

#### Nag Notices ####

This plugin generates multiple [Admin Notices](https://codex.wordpress.org/Plugin_API/Action_Reference/admin_notices) in the WP Admin dashboard. The first is a notice that fires during plugin activation which recommends several related free plugins that we believe will enhance this plugin's features; this notice will re-appear approximately once every 6 months as our code and recommendations evolve. The second is a notice that fires a few days after plugin activation which asks for a 5-star rating of this plugin on its WordPress.org profile page. This notice will re-appear approximately once every 9 months. These notices can be dismissed by clicking the **(x)** symbol in the upper right of the notice box. These notices may annoy or confuse certain users, but are appreciated by the majority of our userbase, who understand that these notices support our free contributions to the WordPress community while providing valuable (free) recommendations for optimizing their website.

If you feel that these notices are too annoying, than we encourage you to consider one or more of our upcoming premium plugins that combine several free plugin features into a single control panel, or even consider developing your own plugins for WordPress, if supporting free plugin authors is too frustrating for you. A final alternative would be to place the defined constant mentioned below inside of your `wp-config.php` file to manually hide this plugin's nag notices:

    define('DISABLE_NAG_NOTICES', true);

Note: This defined constant will only affect the notices mentioned above, and will not affect any other notices generated by this plugin or other plugins, such as one-time notices that communicate with admin-level users.
