One of my little pet peeves is how people use their dock on their Mac.
Here’s my logic. What do you do most on your computer? You read web pages from top to bottom. Because of this, your page is maximized from top to bottom and you spend most of your time scrolling. There is usually extra space to the sides of the page.
Why then, do you take up extra space on the bottom of the page with a dock? You are constrained vertically but have surplus horizontally. It makes so much sense for you to have your dock on the left or the right.
If you have it on the bottom and set to hide that solves most of the problem, but because you scroll so much up and down, you can hit your dock by accident a bit. But it works.
My rant for the day.
