A way to quickly disable mobs, changing spawn rates and mob caps without editing config files or looking up IDs.

This mod has an in-game menu accessible from the Mods menu via the config button or by pressing 'K' or by typing '/easymobspawncontrol gui'. In that menu, you can view all mobs or recently spawned ones, reduce spawn rates, or ban a mob (which removes existing ones from the world and prevents any future spawns), no restart needed.

Guide:

• Spawn rate is the rate at which the game tries to spawn a mob.
• Spawn cap is the limit of mobs that can be spawned near a player; it scales slightly with the number of nearby players.
• If you reduce the spawn rate of a frequent mob, you create an opportunity for other mobs to fill the spawn cap. This is why setting all mobs to a 50% spawn rate does not reduce the total number of mobs. To reduce/increase the overall number of mobs, you need to change the spawn cap.
• The 'In World' tab lists current mobs and their counts, so you can spot frequent ones and adjust spawns or bans.
