During my org-mode research I found a couple of cool dired stuff in Emacs. It really is amazing at what it can do.
examples:
%m - to mark files by regex.
^ goes up to parent dir; > forward subdir, < backward subdir.
super cool: activate read-only with C-x C-q. Now you can move around and change file names & dirs as if they are text lines. C-c C-c : accept changes.
s to sort. Did you know about C-u s? specify options (ex: -ls sort by size)
Z to zip; hit enter on a zip to view contents.
