I don't know whether you would like to disclose the whole source and what you would do if the product takes off, so didn't explicitly ask you to open source. But yeah, show users what was sent would be helpful, better if there's some way users can verify.
I'll think of a good way to do that. Love the idea of a ready made demo project, which will force me to see if there is a good use case for the thing. Appreciate the useful feedback.
