Scribble - A Diagram Editor with a Minimal Interface

Existing CASE tool diagram editors have large, complex, and sophisticated graphical user interfaces. Because of their size, these interfaces are difficult to learn and hard to use. A minimal interface for a diagram editor provides only the essential behaviour required by the user in the simplest possible manner. Minimal interfaces are smaller than traditionalinterfaces, and should be easier and quicker to use. 1. Introduction A COMPUTER AIDED SOFTWARE ENGINEERING tool (or CASE tool) is a drawing tool used to produce and manage diagrams representing a software system's design. A CASE tool typically embodies the definitions of one or more software development methodologies. The tool allows a designer to enter diagrams in the method's notation, checks the diagrams for consistency, and may generate code or produce diagrams from pre-existing code. Unfortunately, providing information to a CASE tool often serves to subvert the design process. For example, Jim Coplien [3] recommends that key..
