The redstone crafter: feature 1 in the upcoming update redvolution

All of us  players pass by a time where we want to finish crafting rapidly,and since it is usually a long process why not automate it? So maybe its time to turn the good old crafting table into something better. The concept of this crafter requires chests with certain resources, hopers to put items in the crafter and another to take the items from the crafter since it has 0 srorage space. The concept of the redstone crafter is the following: 1: You select the wanted recipe 2: Connect the input and output hoppers 3: Fill the chests with the required materials 4: Power the crafter  with a redstone signal and you are ready to go!Crafters do a sound when they are not crafting meaning it is low on resources. It requires a crafting table two blocks of redstone two redstone dusts two pieces of glass and a hopper. Note that it may only craft one item and cannot be changed, so be carefull! Also this is only part 1 of my idea since its sooo long, btw hope mojang adds my and many ideas to the vanilla .
