Hiding title bar

[cgdsyldrm]

Hello, first and foremost thank you for sharing this beautiful diy synth with us.

I got everything working except for hiding the title bar with config.yaml. I suppose the way how it's done has been change since then. I couldn't make it work somehow on Bookworm version of pi os.

$ nano ~/.config/LMN-3/config.yaml

config: show-title-bar: false

Is there any solution?
