It wouldn't be hard to make the navigation tabs at the bottom stand out better with a colored line, but it would cost a couple of pixels' worth of vertical real estate. I'm just not seeing their relative lack of prominence as a problem, though, because I've had no trouble managing them — and I do have very poor near vision. New glasses I'm picking up this evening will help a little!
I only get half the credit card ad when the during-travel card is visible. But since I don't react badly to the advertising, I doubt I'd feel differently if more of it was on screen. I can't ignore ads on TV or animated ads on web pages, but stationary ones are nearly invisible to me.
