FAQ

Q: Why hide F3 elements from other mods too? Did the mod authors not include them on purpose?
A: While some mods add elements that are useful for debugging, to most users these don't matter and they just distract from what is more relevant to most players. If you want to report an issue for one of the affected mods however, make sure to turn on their debug info again if they ask you for an image!

Q: Can you add a toggle for ImmediatelyFast?
A: ImmediatelyFast already has a config option built-in to disable its debug info.

Q: Can you add a toggle for another mod xyz?
A: Open an issue on github with the mods name so I can look into it.

Q: Neoforge/Forge version?
A: Not planned at the moment. For now Sinytra Connector works.
