Can you add an option to modify end command? If I do /end my bungeecord server close xd

For now you can use namespaced commands:

/minecraftmanhunt:end

(or something like that, can't remember right now!)

If you use commands.yml, you can change it to a different command. For example, if you wanted to change it to /endgame:

  endgame:
  - end
