PLEASE make the text as wide as the user's screen.
(Why pretend I have a 17" monitor, when I have 22"???)
PLEASE don't just "chop off all the lines"... and then "add a horizontal scrollbar".
Doing so makes it VERY difficult to see the ends of any lines... if you have more than a full vertical screen of code.
Try to view the end of line
#1... when the horizontal scroll-bar is 200 lines OFF the bottom of the screen.
