I made a collection called “re-ordered end” in which, as you may expect, I re-ordered some of the scenes in my radio play just to see how it would flow. When I want to read them in a scrivening, the scrivening view reorganises then into the original order. Same goes for corkboard and outliner. Is this yet to be fixed? Or am I misunderstanding the use of collections?
Ah ha ha…that’s a bug. 
It should work as you expect. I’ve got it on the list.
