Tip: add recently used apps, docs to OSX Dock

What I Found

You can add a Recent Items stack to the Mac Dock with a Terminal command, giving you quick access to recently used.

If your Mac Dock has turned into a long row of app icons, this is a simple way to clean it up without losing quick access to the apps you use most.

The quick answer is that macOS can show a Recent Items stack in the Dock. Once added, it appears near the Trash, and clicking it shows your recently used applications.
