Thanks, I used gentoo quite a bit back in the day! Today I don't do enough file management to bother going outside emacs dired :)
Just to add some context, as far as I remember, gentoo was pretty similar to how DOpus worked on the Amiga until version 5, when it went from being a classic "one window, two pane, rows of buttons" thing, to arbitrary numbers of independent windows. DOpus 5 was really neat and powerful but also quite a different experience, more like its own desktop environment really. I hope I still have the ring bound manual somewhere...
