I think that Recoll could be smarter hiding duplicates. I often have several duplicates of an email in different folders, and Recoll shows them all. I guess that using CRC to weed out duplicates is too precise, and there should be more fuzziness. Maybe fuzzy duplicates should be hidden behind a link or button instead of being eliminated.

Duplicate data display can be helpful to some.

I previously used topic subdirectories for storing biological research reprints, multiple copies dispersed to the topic as applicable. Now I use RECOLL, and the duplicate displays are a great help in deleting unneeded stored files.
