If the Quickbar is not enough, create toolbars that can hold items and tools and be positioned anywhere you like.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
A nice feature would be to set up a keyboard shortcut and/or add a button in the top left corner to hide all toolbars. This option would be useful when critters attack, allowing for the widest possible field of view during combat.
