Idk if it’s already been mentioned or planned, but a “weapon wheel” style UI selection for items would be nice. Hold a button to bring it up, drag mouse, or analogue stick, release to select.
Being able to determine where things are in it would be great too - something to the extend of a “ custom wheel layout” option in the inventory to clump specific themed items together, eg: all fire related items on the left, and all lightning on the right, with consumbable potions at the bottom.
