Function Permission Level
This is a simple mod that changes the function-permission-level to 4 in integrated servers (i.e. single player and LAN).
The mod is intended for data pack developers that are making data packs that go into servers to be tested easily in single player or LAN worlds. The creator of this mod does not encourage you to use this as a runtime mod.
Notes
This mod only changes the permission level in integrated servers, and thus only affects single player and LAN worlds. Installing it on servers has no effects.
On servers, you can simply change the function-permission-level option in server.properties to achieve the same effect.
