First i had a bug with even opening File View Edit at all; but toggling File View on/off seemed to fix that i think.
So now amongst such a plethora of settings, many of which are somewhat obscure and opaque, the ONE very normal setting i wanted - COLUMN ORDER - which should be WAY easier to find and to do - DOES NOT WORK.
I mean that if i click on the up/down arrows - which i assume sets the column order - nothing happens. the arrows do not work.
so unless there is some other obscure non-apparent way to change the column order, I CAN'T.
