This “name-something” functionality for import of 3D scenes is quite handy. https://docs.godotengine.org/en/stable/tutorials/assets_pipeline/importing_scenes.html

I don’t know if shaders fall into this category, because everyone knows that it exists but I always feel like many people are afraid of trying to work with this and so just skip this entirely… And of course this is not limited to Godot.

You can make use of the operating system’s own text-to-speech systems, either as an accessibility feature or to create old-school voiced games. https://docs.godotengine.org/en/stable/tutorials/audio/text_to_speech.html It apparently should work out of the box on Windows and MacOS, but not all Linux distros will have the proper packages pre-installed.
