Jason Conger has just released a web-based tool he's calling the "Visual MFCOM Explorer." It's available here:
This tool solves the age-old problem of trying to pour through the Citrix SDK documentation to figure out which objects, properties, and methods correspond to what you want to do in the Presentation Server Console (PSC). It works by showing a graphic image of the farm properties PSC window which you can click on, and arrows and labels show each option (checkbox, text box, etc.) along with the appropriate MFCOM reference.
Very cool Jason!
