Let me put it this way. In BG3, I spend a TON of time in two places; Item Management and Hotbar Management.
Why?
Because in order for it to be organized, you have to rearrange both over and over again, every time you get something new. And this is EA only.
Here's my fear about the current hotbar:
Wizard at level 8 may know 20ish spells and probably prepared 10. 10 spells and every time you sleep you might switch out a prepared spell or 2. Add to that spell scrolls, special abilities, items like potions and throw them all on that tiny hotbar set. Now multiply that by 4 party members. Now include that with Item Management. How much time will a player spend just sorting it all?
