I'm not sure if this is planning on being added, but it would be nice if your party members nearby intervened in areas where they're better suited to it then whomever you had first interact with the merchant/townsperson/vicious owlbear/whatever.
Like, I know Astarion is kind of a selfish jerk... but if my myopic fighter can't notice a small grunting child open a hatch half a meter away Astarion could still say something rather than just stand there.
I don't like feeling like I have to make a skill-check character for all interactions when I have a diverse party right beside me, or try to guess which character will be best at talking to some random in town. It makes it feel less like an adventuring party and more like I'm being followed around by chat-bot murder-hobos.
