Snowballs Leave Top Snow Where They Land When Thrown

Snowballs are very useful for certain things like sports and aiming but a way to see where your snowball landed and to be able to pick them up (unless they hit another mob) would be especially helpful for accuracy sports, redstone, and minigames. Like arrows, snowballs would be renewable, but only if you missed your target. Because of this, you will not need inventories full of snowballs if you want a harmless version of the bow and arrow with a shorter maximum distance. Its redstone uses could be the result of forming top snow which would be detected by an observer which would be useful for activating redstone (including flying machines) from a distance. Also the ability of top snow layers to stack, and when stacked 8 times it creates a solid now block, snow could be used in various redstone contraptions. For example, once a redstone circuit fires 8 times and a snowball is fired from a dispenser each time, a redstone signal can then pass through the newly created solid snow block to power whatever contraption you need. This same contraption could also be modified by using multiple dispensers to fire multiple snowballs every time the circuit fires. If a snowball hits a wall the top snow should be placed at the block it hit and then fall as top snow normally would when the block below gets removed.
