I was thinking it would do exactly the same as it does in the Finder - duplicate the selected item and place the copy in the same place as the original, appending a suffix to the filename to avoid clashes. My reasoning for this request is that I sometimes want to have two or more versions of the same photo with different post-processing applied (B/W, different crop, etc) and this would simplify part of the process. I can use the copy command and copy them into the original folder, so it's not a huge, urgent need that must be filled to avoid disaster, but it would be nice to have a one-click solution
. I was also interested to know if it could be useful to others, and I was guessing it would not be too complicated to do? (I'm not the expert though!)
