I don't really like the narrator talk to me whenever I want to exit Minecraft, mainly because the option menu is already there so the narrator is kinda useless, unless taskkill

Will there a config menu to turn on/off this mod instead of uncheck this mod and then re-run the game?

yeah configured isn't on 1.19.4 yet so I guess I have to wait 😥

You can use Configured for managing the config in-game.
There's a config file you can manually edit if you want that instead.
I can however make a toggle for the narration at some point.

Configured is a mod that adds config screens to mods that use a supported config library.
It's for Forge and Fabric.

I think I would prefer a configuration menu open via Mod Menu more, I don't seem to see it
yet I don't know what "Configured" you mentioned is...

I can add a config screen, but then I rather would use my library mod for making the GUI, meaning it would have another dependency. And I want this mod to have as few dependencies as possible.

Done for 1.20, not sure if I will backport it to 1.19.4 tho.

some might be still on 1.19.4 because lack of mod supports ig,
1.20 just came out tho
