Module: views_bulk_operations
One of the useful Web patterns I've been noticing has to do with item lists and bulk actions. Given a list of items, add a checkbox in front of each item, and let the user select an action to be executed on the checked selection. Specifically, I've seen it in phpMyAdmin, Mantis, and Google Mail.
This module provides a solution. It comes as a Views style plugin called "Bulk Operations View", selected in the "View Type" control of the View editing screen. This new style creates a form around the view, adds a checkbox in front of each element, and exposes the available Actions as well as all node_operations provided by loaded modules. When "Execute" is clicked, the form asks for confirmation then applies the selected action on all selected nodes.
