I can’t seem to find it anywhere to find out just what it’s for! 
It’s not on the site & it’s not in the forum. At least not when I used the search functions on either.
Any hints, clues or… info?
Sounds like you got elected new MX guinea pig. Have fun testing. Hopefully you get some great results.
So, what are you waiting for? Try it and tell us all about it!
Have you used it yet???
