Thank you Sebastian. But that's not quite enough information.
I still don't understand how to create _nodeGUI and _nodeMaster.
Here is my entire working GeDialog plugin with a User Area attached to it.
I'm trying to figure out how to use the UA as an xpresso window. But I'm having trouble understanding how to set up the basic framework for it.
