DualHotbar Reworked

This is a fork of RebelKeithy's DualHotbar that attempts to fix all the issues present in the 1.12.2 ChrisLane port.

About DualHotbar

This mod allows you to use multiple rows of your inventory as hotbars at the same time. It can be configured in different ways to render them stacked and/or next to each other.

The slots are taken from the top row of your inventory going downwards.

There are 3 ways to select an item from the new slots:

You can simply scroll with the mouse wheel and cycle to items
You can double tap the number key to cycle to the same slot between hotbars
You can hold a configurable modifier key (ctrl by default) and the slot number

You can also use the mouse wheel and a configurable modifier key (ctrl by default) to swap full hotbar rows while in stacked mode.
