Now, there's a case in point. As this was only a comment/opinion I was sure I posted it in the Speakers Corner Forum. Obviously not as it is in the Helproom and it is definitely not a call for help. Apologies.
"reduce the visibility" do you mean there wouldn't be many thread titles on view?. That would certainly apply to me as I only have a 14" monitor. Maybe the Left hand column could be static then and the Search box put back there where it used to be?
