Threat Explorer: UX enhancements, URL clicks tab and customizable export

THANK YOU for adding Return Path, Return Path Domain and the Authentication options for filtering emails - this is really helpful when diagnosing errors with email authentication protocols, like SPF.

However is it possible to have this data available under 'Customise Columns', and 'Export'? At present those fields aren't present which makes it hard to validate that the filters are working correctly, and manipulate the relevant data?

Great work so far though!
