Duplicates: Delete from de duplicate module

[Gamosphere]

I've finally figured out how to create a duplicate but to my surprise I found out that to delete duplicates you can only to it when you are in the lightroom.

1. Am I just no seeing something ?
2. If point 1 is no then does it makes sense not to be able to delete them from the darkroom view?
   Personnally for me it doesn't
3. I guess a trash box could be added like we see in the snapshot mdule

what's your view?
