Really amazing work firstly. I had a suggestion to enable discussion in the Github repository so that interested users could discuss about potential uses etc. https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/enabling-features-for-your-repository/enabling-or-disabling-github-discussions-for-a-repository
