I couldn't agree more. After I was exposed to 'sam' in 1987, there
was no other editor.
I was, however, heavily involved in the porting of 'pads' and 'pi'
to Solaris and Linux, and 'pads' has a 'move' operation, distinct
from 'resize/reshape'. I had sometimes felt the need of such an
operation when I had a large samterm open with lots of open files,
so, with no pretensions to originality, I took the code from 'pads'
and put it into 'samterm', and it was trivial to add. For which I
should perhaps apologize to the author of 'sam'.
