Didn't really take the time to look. Would rather figure out what
it does and re-write it in C.  :-)

Would be nice.  I wold like it to support VT100 (or better) rather
than just ANSI which is display only.  I would like to see the arrow
keys, function keys and maybe even the keypad work under OS9.  I am
looking at other screen editors, too, Not everyone likes EMACS.  :-)
