Am I the only one that gets overwhelmed when I use my monitor in portrait? Isolating the web ( or code ) into more bite-sized chunks gives my brain one thing to focus on at a time.
You could also resize your browser window to not occupy 100% of your monitor's real estate.
But it's fine, this is a pretty good suggestion that'll increase ad sales because it'll help convince everyone that the fold is twice as far down as it actually is.
No thank you! With wide screen monitors, I can have multiple windows adjacent to each other.
