Peter,

If you mean place a widget on each page overlaying that region of the system bar that has the activity label, that would do it. I used to do that before I saw the note in the developers guide on CF.activity().label. It would be nice if the other properties (geometry) were also available. Being a coder at heart I tend to do things in code and using graphics to do what is trivial in code always appeared strange to me.

I suspect as a minimum if you changed the activity label in prontoscript you might alter the extender messages. Not having an extender I can not say.
