> BTW a horizontal resolution of at least 2048 would be important because most websites do not shrink below 1024 pixels horizontally. (Definitely not down to 1920/2=960, let alone 1600/2=800!) That's when the ridiculous horizontal scrollbar appears.
Hmm, I regularly use a browser window split in two on a 1920×1080 screen. I rarely have to move a browser window to a separate workspace to get a full view of the page, but it's not as often as this would make one think. On my 1440x900, yes, it happens a lot. I do have bindings to modify the split location, but they're probably among my least used bindings.
