Please make dispensers better

Please make dispensers better. Some ideas to get you started:

• Make dispensers place all blocks
• Make dispensers able to teleport with ender pearls
• Make dispensers able to shoot trinitrotoluene (TNT) really fast to make really easy tnt cannons
• Make dispensers able to use spears
• Make dispensers have a toggle to dispense everything at once, making dispensers more useful
• Make dispensers enchantable
• Make dispensers work with cauldrons
• Make dispensers able to plant crops for automatic farms

These are just ideas. All I actually want is an actually useful dispenser rather than a slightly gimmicky more expensive dropper.
