It has been so very long since I’ve used the Dock that it always comes as a surprise when it comes up in macOS UX discussion as I forget that it exists. Can someone explain how it is useful to their workflow?
I have it hidden on the left so it does not take space. Even though I have shortcuts to open all apps. It is helpful for managing windows when I have many windows of the same app minimized.
defaults write http://com.apple.dock persistent-apps -array-add '{tile-data={}; tile-type="spacer-tile";}'
Very useful for organizing icons.
