Don't get me wrong, your work on this extension is a masterpiece, small wonder that Evan wants you to integrate it into App Inventor.
I can suggest the examples you have already made. The issues:
- Incomplete. SAF is baffling when you first see it, so examples should actually work stand-alone.
- Old version Blocks used.
- No introduction to the example describing what it's goal is.
- Unattached Blocks
- Anonymous inputs
- Unreadable images
If you make more comprehensive examples, there wouldn't be so many posts from people asking what they have done wrong - including posts from fellow Power Users.
