Add the offhand, new gamemodes such as , hardcore - when u die u never respawn, lifesteal - if u kill someone u get 2% of their hp and if u do /withdraw u get 2% of your hearts as a item. more below

also add a new command such as /leaderboard \1\ \red\ MOSTKILLs \2\ ------------------------- \3\ ["variable":"kills"{5}"] so it will look like this at the right of your screen MOST KILLS player359 player530 3.player642 4.player456 5.player410 and this could be costumisable but idk how so PLS AD!
