If/when this is implemented, it would be slick to have a “Help me deduplicate” experience that displays the “best” asset with a variant and asks user to confirm deleting the worse one (or delete the “best” one and replace it). The majority of related thread Deleting / hiding photos - #3 by mrm seems to be addressing deleting entire assets, not variants of assets, but @codepoet did mention
I’d like to be able to verify the duplicates in a side-by-side and then delete the “other” one
I think you could use the same “Delete” action you already made for managing entire assets, but I do not think the “Archive” or “Remove” actions would apply.
And of course the variants would not actually be deleted from disk until you click the “Empty trash” button from the “View trash” search.
Lastly I think the “View trash” search should have some indicator differentiating between variants and whole assets. And the variants should include a button to compare again with the “best” variant.
