What does the Tablename.config display?

The TableName.config is specifically designed to display the configuration list view of a table directly within the Content Frame of the ServiceNow interface. This is a useful feature for administrators and developers who need to manage and configure the settings of different tables. By accessing this configuration through the Content Frame, users can easily work with the table's field settings, access controls, and dictionary entries in a streamlined environment without cluttering their workspace with multiple browser tabs.

This focus on the Content Frame allows for a more integrated experience, where changes can be made and reviewed without navigating away from the primary task at hand. It also emphasizes ServiceNow's design principles, promoting a single-page application feel where different views can be managed within the same window.
