Jump reduction effect and choice to disable jumping.

Hello. My name Is gamerhook053 and I'm one of Minecraft players. I have wondered about something... I saw that player can run from danger faster with bunny hoping faster than normally running. And I think it will be good to add some effect that can affect your mobility (so combination of slowness with no ability to jump), which will make movement a bit harder and players will have bigger problem with fleeing from enemies. And for map creators will be good to add the jump reduction gamerule. The map makers can just reduce or turn off jumping for a bit realistic feeling and for making their maps longer or more complex (which in my opinion is good idea). I think it's pretty good idea mainly for content creators and for making survival more SPICY. I'll end it here. If You're reading this, thank you for your interest and I hope you'll like the idea. Have a nice day. gamerhook053
