Extended Product Grid with Editor for Magento 2 : Where Is User Grid View Settings Stored?

Hi,

You can save the User Grid View but where does it go? There is no table that I can see this goes to, I think with M1 there was and you could tidy and/or duplicate the views for other users (with care of course)

Thanks for any pointers
