I would change to a skin with a much wider area for the main content due to how (for me) seeing code on the lines it is supposed to be on is nicer. You might have to build a custom skin though because it seems lately all skins are into the "you will only have this many pixels" for width.

Thanks EdB, that's a very good point. I can also break the lines of the code into smaller (ie narrower) segments; really I should have done this already.
