I often work with DVRs, usually using typdefs or classes for the underlying data.
It's a serious pain to access the typdef or class from the DVR itself (control, indicator, or wire). There's no option for accessing this through the menu, and I often find myself dropping code in my block diagram to output the data type, then right-clicking on the data type and then from that menu opening the typdef or class.
The request: add a menu option for "Open Data Type Def." or "Show Data Class Library" to directly access the underlying type if it's a type def or class. This menu option could be exposed on wires, controls, and indicators.
