Non flying gravel and sand.

If you get angry by falling gravel in mines or sand in deserts, vote here! My idea is: add button in game rules or on page where you can write seed for world "non flying: sand and gravel, gravel, sand". For noobs it's great, cuz they maybe play very bad, and if on them all ways falls gravel or sand, they will be sad or anger (it's my idea) and this button for them will be very helpfull, and pro, who does challenge, for example: Minecraft, but you have only half hp. And they can be in mine, and gravel fall on them and kill. Maybe this function will helpfull for someone, thank's if you read this).
