What does Simple Discord Rich Presence Mod actually do?

It tells Discord what you are doing in Minecraft, reporting whether you are on the main menu, loading, or playing, and which dimension you are in. It deliberately avoids the long list of options that heavier presence mods carry.

Does it show which dimension I'm in?

Yes, it displays your current dimension in your Discord status with a matching image for the Overworld, the Nether, and the End. The status updates when you join a world or move between dimensions.

Do I need to register my own Discord application for it to work?

No, it ships with a working Discord application, so nothing needs registering before it does something useful. If you would rather use your own art, you can drop your own Discord application ID into the config.

How complicated is the config file?

The config file is short, and the mod works with its defaults out of the box. You only need to edit it if you want to use your own Discord application ID or change other settings.

Can I customize the status beyond the defaults?

Yes, there is a KubeJS hook that lets you set the status yourself from a script. Otherwise, the mod reports the main menu, loading, playing, and your current dimension by default.

Does it detect when I'm on the main menu versus in a world?

Yes, it detects the main menu and the moment you join a world, so the status changes at the right time. Each state is shown with its own icon.
