Nice one. Thank you! It looks as if ".browser", ".automatic", ".navigationStack" each eliminate the extra (left hand) back button nicely. Choosing ".editor" is the odd-ball. I've not made sense of the documentation on this - but - for now I'll run with .automatic. Thanks again.
Correction....
When MULTIPLE "Products" are opened in their ImageScenes, from the main scene using the long press + "Open in New Window", then dismissed using the close button "x", ImageScenes are not deleted - rather it seems that they either swapped, or deleted and immediately restored.
