No problem at all - I fully understand why you created the plugin and why it works for you. As I said, if I were you, I would just consider making the pull request to make the currently private functions you need public. Your use case makes sense and this way everybody will be able to use your plugin.Thank you Jiri for your advice! I will make the pull request and update D. Perhaps you can check it out then.
Also, good luck with your work! The space program seems really interesting!
