The example output other than that though consists of images easily produced in MacDraw or MacPaint, copy-pasted into MacWrite documents for layout. All the fonts used are built-in Mac system fonts.
And the big game changers that made that possible for a user with minimal training were WYSIWYG onscreen graphics, universal copy/paste (plus the ‘scrapbook’), and consistent availability of ‘undo’.
Also not to understate the value of the Finder, with folders and documents that you could see, and the clever undoable ‘wastebasket’ metaphor that also gave users confidence about what files were there, what files they were operating on, and what files they were deleting.
It was completely gamechanging.
