This plugin will display a small ??? icon that links to either the definition or the translation of the word. The plugin is a no-brainer to use: [define:dog] will define the word ?dog? and [en2fr:dog] will translate the word ?dog? from english to french. [wikies:dog] will show the Wikipedia article for the given word in spanish (es). Dictionary.com is used to define words, as it has definitions for technical terms too. Translation works with Google’s translation engine.

It’s nice to pre-populate terms, content or have the ability to only OCCASIONALLY run actions.
In the past, I’ve had to manually use special $_GET variables.
Not any more! This plugin provides a simple interface for admins/super admins to fire a special hook. You can easily hook onto that action in order to perform your infrequent or expensive logic.
This could be anything such as pre-filling content, auto-creating terms, updating the database in a certain manner, talking to or updating an API, etc.

Seeder

Perform heavy / infrequent actions in a controlled manner.
