Geez, I use it all the time. I use it so much it's like breathing, I don't even think about it. In fact it's such a part of my way of working that I didn't realize that's what the article was talking about.

Double left-click and it's immediately in the buffer, because why else would you double click text? Middle click and you're done. Easy peasy, and I would hoist the black flag and start slitting throats if it disappeared.

Fortunately for me I use LXDE, where they seem to have resisted making a career out of churn. I really don't care what's in front of me except for what I'm working on, and I don't want to be aware of my DE. To me it's like adding features to a coffee cup. Once you're drinking coffee why would you care at all, as long as the handle still worked.
