Secondary Tool Bar

With the influx of new items, we're finding a need for more space on our tool bars and inventory more than ever before!

Could there be a second tool bar at the bottom of the screen? Each tool bar could be switched by pressing the Tab key and then using the scroll wheel to select the items as usual. I'm not sure how these operations are done on other platforms, but this would be for PC (Java).

The delineation between these toolbars would be up to user preference, but I would assume most users would use one for fighting (sword, bow, mace, pick, shovel, axe, food, potions, wind charges) and the other being for building and actions (blocks, items, shulker boxes, etc.)

The other solution is just to add more slots to the existing toolbar and inventory and/or add an advancement opportunity for the player to achieve this through crafting harder-to-obtain items.
