Problem: you always should hold quick item/food button and scrolling through different items list/food list. That may break combat tempo or just generate tedious feeling.
Suggestion: add availability set up to 8 buttons for items/foood (F1-F8 & etc).
that sadly only works for kb+m players. where do controller players get the 8F keys from 
Yes, but that still doesn’t negate the point that surfing through the mouse wheel amongst the multitude of items/food with a button jammed on the keyboard during combat can be tedious or even break the pace of the battle.
For kb+m users this would be a workin solution. If it also should be applied for controller players, I remembered how it was realized in Elden Ring wwith help of quick slots and pressing two buttons at the same time for use items from that slot.
I think this is a design decision; you’re supposed to choose what you take with you and what you really need, rather than just stuffing everything into your inventory. But if Moon decides to use hotkeys, why not.
i totally agree with @VictorvanCleef here. i chose which meal i want to quick use and select it for my quick slot. in 99% of cases that is enough, and in the rare case i have to switch, i hold a button and scroll 2 slots further.
and proposing a supposed solution that only works for some players, makes it easier for them, but makes it harder for others is not really a solution
