Show detailed information about the conversations in your gmail. This extension shows a tag if the domain of the email sender is from a private company. Free email domains like @gmail.com and @hotmail.com are filtered out. But emails from employees with a company domain (such as @linkedin.com) will be tagged in the list view.
