Tenth Slot

Ever found yourself frantically clearing out a hotbar slot just to free up your hands? Tenth Slot solves that instantly. It adds a permanent, always-empty tenth slot to your hotbar, giving you a dedicated bare-hand position that is always one keypress or scroll away. No more juggling items, no more accidental placements, no more interrupting your flow just to swing an empty fist. It fits seamlessly into the vanilla HUD as if it were always there, and stays completely out of your way until you need it.

FEATURES

Tenth Hotbar Slot	Adds a permanent tenth slot displayed as an extension of the vanilla hotbar HUD
Empty Hand Toggle	The tenth slot is a dedicated empty hand position that always shows a bare hand with no item model
Permanently Locked Empty	The tenth slot can never hold an item. Items picked up from the ground, received from containers, or inserted via commands are automatically redirected to other available slots
Keybind Support	Jump directly to the tenth slot with a dedicated keybind, separate from the vanilla hotbar number keys
Seamless Scroll Wheel	Wraps through all ten slots naturally. Scrolling past slot 9 goes to the tenth slot, and scrolling past the tenth slot wraps back to slot 1

CONFIGURATION

Changing the Keybind:

Go to Options → Controls → Key Binds
Scroll to the "Inventory" category
Click on "Hotbat Slot 10 (Tenth Slot)" and press your desired key (default: 0)
