I'm also wondering why you'd want this actually. I can create the most wonderful layout, but what *I* think is good might not apply to someone else, so he might want to fine-tune things. Why block that feature? I myself have literally put 12+ hours into my layouts for the Roland synths, but wouldn't want them to be locked. I created them primarily for myself, but hope that others will enjoy them too, without limitations. It would only place more 'burden' on me if I'm the only one that can edit them...
