I think i can try to do this

What is this supposed to add?

Wait, what matthias says, I could be wrong

Okay, in this case, should I close this issue or leave it?

For now we have only this available keywords to localization

{
    "gamerule.doContainerDrops": "Do container drops",
    "gamerule.doContainerDrops.description": "Controls resource drops from containers",
    "gamerule.doBlockUpdatesAfterEdit": "Do block updates after edit",
    "gamerule.doBlockUpdatesAfterEdit.description": "Force update blocks after editing them in WorldEdit"
}

I'm planning to add more keywords like command.error.blockNotHaveBlockState etc.

Yeah, I dont think thats planned for now, not sure tho

Yeah, let's wait until he answers

If this also changes the feedback system to translation keys then i dont mind this being implemented

You mean this?
Because i want to implement it like this, or Feedback also saves message to telemetry data?

Feedback.invalidUsage("command.copystate.feedback.notHaveBlockstate")

yeah

the translation keys should probably be in some utils class but yeah

Hm, I'll think a little about how it will be possible to implement this in the best way, and if I come up with something, I'll reply here
