IDEA: duplicate jpeg files lister on the basis of the "date taken" attribute

[basc]

I'd like to see a 'duplicate (jpg) files acumulator on the basis of "date taken" programme.
Selection done with typing properties, directory locations with wildcards?,which is perhaps quicker than filling out a series of radio buttons, to isolate the 'keep or move' list, however you feel comfortable.
Warn when all instances of duplicates are selected (or matched).

Thanks again,
basc
