I’ve added all gamerules including place holders for future gamerules (player sleep percentage and freeze damage). I’ve added an automatic check of all the gamerules when you join if you have “Mod”, if you don’t want the to show up use /removecheck which will give you an advancement that will block the automatic checks for you, there is also a command (/gamerules). Unfortunately the checks do not include digit based gamerules as I currently don’t have a way to do that. I ran out of time today to look into a seed button and will do that tomorrow along with the XP stuff.
