As a user I'd like to be able to craft larger amounts of eyes so that I can make my dragon search easier by launching the eye more frequently without having to worry to lose my sparse items.

• The current crafting recipe requiring a dragons heart and an eye of ender (which requires an ender pearl and blaze powder) seems pretty expensive
• It could be possible to add a structure, a trading option or modify some loot tables to find more of those dragon eyes
• It could be helpful to have an alternate recipe using dragon flesh and an ender eye. Maybe with an in-between step where the flesh or heart can be grinded into a blaze powder similar item like dragon essence.
• Careful consideration has to be taken to balance the availability and the chance the eye is destroyed upon usage
