You know what else would be useful in half-page landscape mode? If you automatically drew a blue line at the bottom of the screen when you were at the top half of the page and the blue line at the the screen wen you were at the bottom half of the page. This could be a selectable setting, since some folks wouldn't like it.

And even better, in addition, if you had manually set the break point, the blue line would appear there, despite any overlap at the top or bottom of the display.
