Lets you override default texts from your admin panel. 
Originally built to override texts from Woocommerce, but also works for all neatly added texts by WordPress Core and plugins. 
 
It will translate all _e(”) or __(”) string calls, so check the PHP sourcecode of the plugin or theme you need to translate. 
 
It will NOT translate any dynamic strings like %s or %d, so “%s has been added to your cart.” is not translatable. 
 
It will NOT translate any strings that contain HTML tags at all. 
 
Some WooCommerce examples: 
WooCommerce “Select option” (dropdown value) setting

Author Bind is a plugin that lets you configure a User ID to override all future added or edited posts/pages. There is a settings page under Settings for this plugin where you can configure this ID.
In addition, this plugin denies viewing author information in the browser. If you try to access any author .e.g. via http://…./?author=1 you will be redirected to home page. the same goes for perma links.
The plugin also will override the error message when logging in to something generic, instead of informing the person trying to login if the username exists. This is currently only in english, and not translated.
