@nebulon Yes, it took a while to figure that out.
The UI is the confusing part, since if you see that screen the first time and it is populated, you have no indication to clear it, or button to turn it off. The logical part is to change what it says, for ex Disallow to Allow, but that doesn't work either
So a UX improvement would be to have a toggle, which only displays the robots.txt proxy content if it's enabled and while off gives a hint as to what turning it on will actually do.
That way the breadcrumbs lead to the loaf of understanding and satisfaction
