Friend And Allay

Gives the allay actually useful abilities.

Vanilla mode maintains all vanilla functionality.

Right click a vanilla allay with an empty hand to put it into friendship mode.  (Right click it again to return it to vanilla mode.)

The allay will now deliver all nearby items to the player.

After putting an allay into friendship mode click on any location (such as a hopper) with a stick.

The allay will now deliver all items to this custom delivery location. 

Or click on any location with an amethyst shard and the allay will remain near this location and deliver all nearby items to it. (If you click on anything else but a location with a stick or an amethyst shard you lose the ability to set a custom location.  Set it back to vanilla mode and then back to friendship mode to set a new custom delivery location.)

If you give the allay a bundle it will act like an item filter and the allay will only pick up items that match those in the bundle (v1.1.0).

No need for noteblocks or redstone clocks to get the allay to deliver to a desired location.

Allays are also much faster so they can keep up with the player when riding a minecart, boat, or horse.

Take the allay mining and have it deliver items to a hopper for shipping up to the surface.

Or have the allay pick up and deliver items on a farm, library, shop, or factory.  No need for complicated redstone contraptions.
