Zoomglass

A Fabric mod that quickly puts a spyglass into your hand with a press of a button. Made for people who prefer roleplaying aspects of a spyglass but don't want to miss out on convenience!

Additionally, you can use a fake spyglass while in Spectator gamemode, or in Creative when you don't have it in your inventory.

The default keybind is z, and you can find it under the "Inventory" section in keybinding settings.

Requires Fabric API
