Custom bulk actions for any type of post
Currently WordPress doesn't allow you to add custom bulk actions. See codex. Adding them is super easy with this plugin.
This is based on solution found here: http://www.skyverge.com/blog/add-custom-bulk-action/ This plugin just makes it more easier to use.
Plugin adds a class named Seravo_Custom_Bulk_Action which you can use to easily define custom bulk actions. See documentation and examples here: https://github.com/Seravo/wp-custom-bulk-actions/
