okay, people need to stop treating digital canvases like an analog surface. It doesn't matter what dimensions your screen is. The paradigm for virtually every application on a computer is to scroll vertically, so practically that space is unlimited.

What people want to do is fit stuff side-by-side and move up and down, rarely ever the other way around. That's why vertical tabs make no sense in most contexts. It's why narrow-width fonts exist, those columns are valuable real estate as soon as you have another window pulled up to the left or right, there's virtually no case where a few rows made a difference.
