Override tostring in VisualD?

[James Japherson]

I'm trying to customize the debug display values.

I've overridden toString in my types but they are not effecting 
the displayed values. It simply displays a sort of json of the 
type. (which happens to be real long and contains a lot of 
indirections, I want to shorten it to something meaningful like 
displaying the relevant values)

Is there any?
