This plugin adds the option to quickly open the block diagram of the called VI from an Actor Framework Message's "Do.vi" by right-clicking on its respective "Send ... Msg".
To identify the clicked subVI as an AF's message "Send" VI, three checks are performed:
1) that the VI is part of a library that contains a "Do.vi" (so rules out abstract message classes)
2) that that library inherits from the AF's "Message" class
3) that it contains an AF Message's "Enqueue" .vi
These three checks are of course, a compromise in robustness and amount of code executed. They are kept as simple subVIs in the code to make them a bit more accessible if ever you wish to change or replace them.
