I am confused about the GTInspector State tab. What is its definition ? I would say that it shows the raw, fundamental, implementation form of the object, in essence what EyeBasicInspector showed. And that additional tabs offer alternative, more user friendly views. Why then does it not show all variable content and only named variables ? Try inspecting a [Byte]String or [Byte]Array. The State view is useless, it just shows self. Some of these have an items view, but not all. How can I inspect an individual character of a String ? Or an individual byte ? Consider a Float. The State view should show the two (meaningless) slots because that is how Floats are (currently) implemented, and then another tab should show the sign, mantissa, exponent view. In the Eye inspectors we also confused these two aspects in a single view, which is wrong in hindsight, IMHO. It should be crystal clear for a user whether a slot is real or an alternative view of describing the same thing. I could propose changes or a slice, but I think we should agree on the definition of 'State' first. Sven
