Core Rules mode is not too much to ask for. DoS2 had like four different game modes. This is a D&D game, Core Rules is a no brainer.
As far as Aesthetics, this is supposed to be a BG game. You would think that you might want to appeal to the classic fans. Setting up a similar interface set up to the classics, immediately tells me where everything is. I know exactly where to look and feel immediately at home.
These suggestion seem actually quite simple to me.
