I have a few ideas for minecraft :D Hope you like. :D

More realism in Minecraft.

-Thirst(Die from thirst like hunger. Drink water bottles)
-Take damage from being in the desert for to long.(Don't take damage if in shade)
-Get tired.(If you don't sleep then you will be dazed and will walk slower)
-Use bandages.(If you are hurt USE BANDAGES(Revives 2 hearts))

GRAVITY
-Block will fall if its not touched by something that is touched by the ground.(E.g. Trees)
