MIDI Guitar 2.2.1 and MainStage - Questions wanted

HI Guys!
I just did a video for the entry level user of MIDI Guitar 2.2.1 and MainStage together, and I realized that the more advanced users will probably have some insights as to interesting features, questions or queries on the subject. I am interesting in any kind of feedback here. In a second installment I am considering including 1) A more thorough walkthrough in setting up a Multi controller patch (with different types of controller involved), 2) The “missing keyboards issue” mentioned in the forum earlier, and solutions. But is there something you’d like to see? Please let me know!
