How is this different than Automated Logout?

This module was originally written in response to Automated Logout's limitations when compared to a set of particular requirements. For example:

• Supports and maintains synchronization across multiple tabs even when tabs are inactive.
• Supports simpleSAMLphp Authorization logout directly.
• Displays a warning on the tab itself upon timeout.
• Adds query string to the logout target allowing for greater customization of theme templates for logout messaging.

Automated Logout was used against the original specification, but did not meet the customer's requirements. We tried extensive patching and customization and only came close but no cigar. There was just too many issue to make it practical. So this module was created. And since it was created, it is shared with the community.
