I have just uploaded the latest Mission-X v1.20.10 build.
It will allow you to program three buttons or keyboards key, to three main widgets: Briefer, Flight Gauge and 2D-Map. I hope it will make your venture to the plugin menu a history ( unless you like it... ).
The latest build has also minor enhancements to the LogicToMonitor element, and it was raised in conjunction with Tutorial 4, so always grab the latest build, when working with the tutorials, or when writing a mission.
PPC machines should use the mac.xpl file, it should be a universal build so it should work on both Intel & PPC machines. Let me know if there are any issues.
Last, Tutorial 4 - Logic, was published, and it gives you a good overview of what can be done and what are the limitations of the Logic implementation in v1.20
I now hope to continue with the next version of the plugin and to add some more features that will enhance the plugin even more. If you have any special feature in mind, you are welcome to post me.
