BG3 interface is mostly this...
What is wrong about that? Its practical, clean and organized. O_o
Good question.
I agree. I think it looks good.

There are a couple of small changes I'd like to see in the way things function. 1) Auto-organizer that works better, 2) the ability to select more than one item at a time, and 3) a potion and scroll icon on the hotbar that opens up and shows all the potions and scrolls, like some of the spells currently do (Find Familiar as an example).
Other than those small things, I'm fine with it.
As far as just the aesthetic goes, I think it looks great.
The last thing I want to see is some overly-decorated, clunky system that looks try-hard and outdated.
