It calls itself a viewer, and that is plainly deceptive when
the program irrecoverably modifies the file with one keystroke,
whether deliberate or not.

One would hope they are. But most viewers I've come across do
not modify the file when carrying out the trivial but vital
operations one would expect to be present: orientation,
flipping etc.

I would also point out that these single dangerous keystrokes
are adjacent to other keys that one might expect to use, and
can use, safely. Eg _ (invert) is next to +, | (flip) is next
(British layout) to both A and Shift itself.

I really can't understand why these particular operations
have been chosen to be in-place; it's grossly incompetent
interface design.

I wonder whether you realise that's a mouse command. Have you
tried holding down Control, then pressing and holding down
both buttons within the prescribed time constraint, then
trying to move another digit on the touchpad to get anything
resembling a precise rightangle rotation?

No, this is an entirely different function from the flip/invert/
rotate functions one expects in a viewer. Apropos these mouse
commands, what's the mysterious "null button" (first in the list)
that's meant to restore the image?

Oh, I see people agree with me. Depressingly, the < and > commands
are legacy baggage, and derf (flagged as "Owner") says they will
be kept. So, my choice, and it's no feh, period.
