What does it do?

Adds a zoom key, can be configured to be like OK Zoomer or Optifine. Or any way you like. Extremely configurable.

Why should it be in the modpack

As of Zoomify 2.0, spyglass integration is present. Allowing the requirement of spyglass in the hand or in the inventory.

Why should it NOT be in the modpack

No server integration. Servers can't control the ability to zoom.
