[digikam] [Bug 374180] Other tags assigned to the picture is disturbing when looking at face tags

[Simon Frei]

Thanks for the screenshot, it definitely helped me understand.
This is however not a bug but intended. The information displayed below
the thumbnail in icon view is specific to the entire image also with
active people sidebar. Only the overlay that allows to confirm/type the
name or discard the face rectangle are specific to the view shown with
people sidebar active.

Regarding your other two questions:
 - There is no way to mark a face but not use this face for face
recognition.
 - There is also no way to separate tags applied to the entire image and
only to areas. Every tag applied to an area (i.e. face) is also applied
as a tag to the entire image.
