Thanks to these two features, PostScript let tool-makers create authoring tools that did not require familiarity with the intricacies of PostScript code.

PostScript had the advantage of fitting the needs of its users fairly well from the start. Then, too, all this authoring effort is far harder than it should be.
Visual tools are far more efficient for most users, most of the time.
