Haven't heard it mentioned here, but a quality of life matter from BG2 Enhanced Edition:
If you select an item in the party's inventory, characters that cannot use that item (due to a lack of proficiency or other reasons) have their portraits highlighted in red, while characters that can use the item in question have normal portraits. This is good for sorting loot without having to check who can do what.

Remember the human (This is a forum for a video game):
