It does feel like a native Mac app and is quick and responsive. Is there a way to modify the key hotkeys to be like Total Commander? At this point I don't want to have to learn another set of keystrokes. I briefly looked at it and hit space to select a few files, and it opened them, and then I hit Cmd+D to get a quick directory and instead duplicated the file. So it seems that a key mapping from us old commander users must have been done by someone.
