What you leave out is often what turns good into great. What you leave out is the difference between something that is either 1) never seen or used or 2) simple, clear, and actually digestable. It’s true for photography. It’s true for features in software. And it’s true for plenty more too.

We are proud not only of the products Apple has shipped, but also the products Apple has decided not to ship.
Editing just goes to show you care.
