I would love for this to happen so please up vote this.
Pretty much Nitrado could, and should, make it possible for server owners to create groups/categories for players. Such as Mod, Admin, Helper, Booster extra.
Then the owner adds players to those groups and they have access to certain admin/cheat commands that the owner chooses
You can already whitelist players, give admin, and ban players. It would be soooooo easy for them to do this.
It would also give server owners a way to reward players with in-game content for Nitrado boosting.
Owners could then make it so that Boosters can use only certain summon/spawn commands to get a certain item, or lootcrate.
PLEASE NITRADO! Make these changes for us server owners! It would be much appreciated by the whole of the community
