Thank you for taking so much of your time playing the demo, and even writing tools for the game!!!
First of all, I received and read your feedback (submitted in-game), I'll address the issue with the "Center Camera" setting as well as additional "Materials Case" interactions!
As for your external tools, you have my blessings to host it on your site (saw the codebase on github)! as long as it's a free tool available for everyone to use!
Again, thanks for taking so much interest in the game!
