How about making an option to have the image in the left pane, and the selection list in the right?  Or have the list at the top and the bottom pane be the image?

This would be mildly annoying, but on some burned monitors, the electron gun gets a set allottment of power for each scanline, and thus, after drawing the data at the left, it draws a faded image at the right.  The varying nature of the images on screen tend to make a streaked image by the time you reach a quarter way accross on these kinds of hardware.

It'd make a nice option.  Never a good default mode, but a nice option.
