Full Metal Jacket seems really promising. Thanks for working on this.

Have you seen Clarity? Yours looks more interesting, but it's another visual programming language: http://www.clarity-support.co.uk/products/clarity/

There's a book on it too: https://www.amazon.com/Drawing-Programs-Schematic-Functional...

There might some aspects that could be useful to your work.

Have you considered what a full 3D version with touch controls might look like?

Do you accept donations?

Donations would be very helpful of course, but I don't yet have any mechanism set up to receive them. If you or anyone wishes to make them, please first get in touch by email (my email address is on http://web.onetel.com/~hibou/index.html). Then, I could arrange to receive donations, perhaps via Paypal.
