Is your feature request related to a problem? Please describe.
Often the file name carries information, which is not visible in the photos app. Switching between files and memories is confusing.

Describe the solution you'd like
Display the file name below the image. It would be perfect if the file name would be searchable.

Describe alternatives you've considered
I considered adding the file name as tag or exif title if the field is empty. But this then is only visible in detail view.
