Mangoverlay is a graphical configuration manager designed for MangoHud. It facilitates the serialization and deserialization of the configuration while providing a user-friendly graphical interface for configuration management. With Mangoverlay, users can easily prototype the layout of the HUD, simplifying the process. For reference, you can find a sample configuration available.
The development of the (de)serializer for the config format is taking place in the serde_mango repository.
