@stormpython Thank you for this plugin! Finally a promising way to drill down on a huge amount of data. Cannot wait for the improvements / bugs to be fixed - I'm happy to support if you need testing.

@t3chn0m4g3 thanks for help with testing. I plan on working on a few of these issues today.

Similar issue with ip addresses - they show as the integer version.
