MxmsSettings.json
From MXMS Wiki

To provide a flexible and scalable environment, we use JSON (JavaScript Object Notation) for all system settings and user preferences. JSON is a lightweight, text-based data format that is easy for humans to read and write, and easy for machines to parse and generate. By modifying the configuration file, you can customize the behavior of the application without needing to touch the underlying source code.
Why JSON
Structured Data: Organizes complex settings into clear, nested hierarchies. Universal Support: Compatible with almost every modern programming language and tool. Lightweight: Minimal overhead ensures that your application loads settings instantly.
