Some years ago there was a project ( http://en.munknex.net/2012/06/new-kde-copy-dialog-first-preview.html ) which introduced some quite handy progress dialog for copying files. The idea was really good (keep copying non-conflictive files while waiting for user input on conflicts with a nice UI), but I lost track on that. Did it get merged in KDE? If not, can we get something like that? Btw, I'm not really sure if this should be tagged under "Dolphin" or under "KIO". Retag if required. Reproducible: Always
