As Letho said at the end of The Witcher 2, "I suppose there's no accounting for taste."
I'm personally very fond of the new UI in The Witcher 3.
And that is to be respected, good Sir.
However, I think the thread should strive to rise above mere professions of fondness or distaste, natural and welcome as they are. A number of aesthetic problems were pointed out and I wish yea-sayers would respond with something along the lines of "That is not a problem because of X" , "No, since Y counterbalances that" or "This fits in/is congruent with/ serves purpose Z".
Otherwise this just turns into something not that much helpful.
