well I just used diff -qr as an example.  In practice I have a few
other commands that do directory comparisions and merges.  I sometimes
use kdiff3, or unison, or some home-grown scripts that deal much
better with renames/moves, etc... :-)

Aaha!  When I have a tab on foo and one on foo/bar, and I copy foo/baz
by yy/dd and switch to tab 2 and pp it into foo/bar, when I come back
to foo the cursor has moved to bar instead of staying where it was.  I
suspect this is caused by the same thing?

perfect... (actually anything at all that gives me the path of any
other tab is fine for me; I only ever need two so even if I have
multiple tabs open I can manage)

please make it optional... mc's look is right boring compared to ranger!

Thanks for looking into it!  Whatever way you can do it is fine by me.
