This approach I think fails to address the real problem: I do not particularly care how I've reached 1/2/3/4 command. The problem comes when command 4 has many options. When you display those in a GUI with default values it is more or less easy for even uninitiated to get a grip. Not that much with CLI or this CLUI. Best tools with complex logic like CAD software usually combine CLI, CLUI and GUI to be ergonomic.
