With the introduction of the new width lines and related features, it would be nice if there was a probe which could be attached to a wire to display the wire width similar to how Static Value does, but without being able to set it (the CC design would define that - this would be purely read-only).
Additionally, a component probe would be nice. I suspect this would be a bit more finicky as different components would need to read widths in different ways (fixed size, 'x', width-defining components like Static Value and Static Evaluator, etc.) but it would be great if it could be done. Most if not all widths I suspect could be just pulled from some wire or other though and the component version would be more for convenience than real necessity.
