Slime block properties

Hi, i'll like to be able to add some slime block properties with a total power on the modification of it, beign able to select if you take fall damage or not, choose if we slide on it or not, choose the bounciness and also if it stick to block or not, also you could do the same with the honey features, this will allow lots more of variety in block functionnalities, we could do jelly blocks, custom slimes, and even some trampolines!
