As in Krusader 2.0 or DoubleCMD, if select files/folders and then copy them to somewhere, the state of files/folders' selection is preserved. With this behavior, I could quickly check that if the files/folders are copied successfully. Or, If I want to move these selected files/folders (after copying), I just perform cut/paste task, without worrying what files/folders need to be selected again.
Turn this off: Settings > Panel > Operation > Unselect files before copy/move.
Thanks!
