I hate comparing BG3 to the first two, but they are a good example of the UI done right. The spell button that opens up a list of spells to cast, the 5 quick use items area, The UI really needs work, Its just a MMO style mess of abilities, spells, and items. Not to be totally negative, I do think some of the UI is great, The party screen, the inventory screen, are fine, the tool-tips could have more info and better descriptions.
