Hey Roger,
Thanks for using Fiddler Everywhere and for your valued feedback! Indeed at this moment. the WinConfig functionality (from the classic Fiddler) is not present in FE. Marking this one as a feature request for eventual future implementation.
Fine. I will continue to use classic Fiddler until that feature is available in Fiddler Everywhere. Thank you.

I use Fiddler to exempt UWP apps from loopback restrictions so that they can use the system proxy. I really need this feature, but I doesn't find it in Fiddler Everywhere.
