There are some mods (for example Quark) that allow players to switch between multiple hot bars.

SwapHotBar is a plugin that implement this feature in a simple way, by changing the relationship between hot bar and backpack: each row of player's backpack can be seen as a hot bar, when the player is in the game, using shift + mouse wheel can swap the items in the next row (or previous row) of backpack to the hot bar, while the current hot bar's items will swap back to the backpack, that form a cycle.

In sum, this plugin has the following 2 features:

• Players are able to swap between backpack rows without open the backpack.
• [1.6 new] Players can turn on or turn off this function by themselves

This mechanism is very convenient in the game. The application scenarios include but are not limited to:

• swapping food, weapons, and tools
• swapping tons of building blocks
• quickly searching for an item
• etc...

Just see the following sample inventory and the GIF to understand the usage:

• Please fully test before use. If you have any problem, please give me feedback as soon as possible.
