Hello.
I think that a chat command should be added called "/afk". This command would freeze the player and stop him from getting killed by zombies, losing hunger, or endurance. My idea is that the command would automatically disable itself once the player tries to move for 2 seconds.
This would definitely make it so that when you gotta go, you don't have to worry. You shouldn't have to worry about leaving the game unattended, it gets annoying that you have to leave the game in order to preserve your status if you have to leave for (x) minutes. It's either leave the server, or screw it and let yourself die + lose things.
Sometimes, when outside traveling and you have to get off for a minute right then and there, you can't help it when a zombie kills you and you lose your guns, and materials - you don't even have a fighting chance.
I believe that this could vary quite a bit. Like for example: Instead of freezing you on the spot & protecting you from zombies it could put you where you are when you first join the server, before pressing the spawn button. That way when you get back you just press play now and you re-spawn.
Please consider this command, it may be very well worth adding!
Thanks,
