First you have LethalConfig which helps you configurate most mods ingame. You sometimes might need to use common sense to understand what makes it server-sided or not.

The mods i don't recommend configurating are: GeneralImprovements, TooManyEmotes, CozyImprovements, ShipWindows, CelestialTint, CruiserImproved, Loadstone, Matty_Fixes_Experimental.

Everything else is configurable and will still be client-sided.

Thanks for reading and goodluck!
