sunflowers r kinda boring (and they have potential)

I think an update for the sunflower would be really cool and make the flower useful!

Seeds: Sunflower seeds could be obtained by putting the sunflower item in a crafting table to get the seeds (similar to melon slices), giving the player a new food source when roasted in a furnace.

Direction: While real life sunflowers follow the sun, the ones in Minecraft only face east. Making the sunflowers follow the sun in game would generally be cool, and realistic.
