What does it do?
When you hit an end crystal, Minecraft normally waits for the server to remove it before you can place the next one. On higher ping that wait is easy to feel. Marlow's Crystal Optimizer removes the crystal on your side the moment you hit it, so you can place your next crystal straight away.
