I did this, and it was great at first. Then I needed more socks, so I bought another batch. Then I had a mix of worn socks and brand new socks. They might look the same at first, but if you take a closer look, the older ones are a little lighter in color and the texture isn’t the same. I later bought a third batch. So now I have a mix of new, old, and really old socks. It actually takes more effort to match socks now than when I had many different socks.
I see this advice posted all the time, so I guess most people don’t care if their socks on each foot are a different level of worn, but it bothers me.
Years ago, I used an extension called Tree Style Tab. It’s better than just vertically displaying tabs. New tabs open as children, and you can collapse branches, so things stay organized when you have a ton of tabs.
