I don't know if anyone else on the forum knows this but I recently discovered the GDScript style guide in the documentation. It's really keen and clean way to approach your GDScript code. I don't know if this will be a help to y'all but I wanted to share it just in case. I didn't know GDScript had suggested naming conventions and general guides on how to structure a code file.
I also Great tool for formatting your code. It's called GDScript Toolkit and I just got it up and running in my project. I think it's also really useful for making things a bit more readable and shareable with others.
Just wanted to share my findings. :-)
