I am a beginner still and was just teaching myself screens today! Im excited to learn more about them with this tool. Thank you for creating it!
Very cool! Unfortunately this pack doesn't have much that's useful as examples for screens. The ones that I included are more or less placeholder copies of the default one.
The magic in this pack happens in the Python logic that runs around the screens. It probably won't help you make nice screens in and of itself, but once you're able to, it should be a force multiplier for your VNs.
