The fixed UI has been a complaint for quiet some time now, so I'm sure Adobe must be aware. Interestingly Adobe have just introduced a choice of UI in the full version CS6 where it’s possible to choose light, dark and variations in between. So watch this space.
Yes adobe does read the forums but they don't always comment on everything and they are quite aware of the complaints about the ui colors and such in photoshop elements.
Hopefully the ui problem will be addressed in photoshop elements 11 in such a way that satisfies both those who like the dark interface and those who want a lighter interface
similar to photoshop cs6 only better.
Does Adobe read these forums and comments?
Short answer is NO. All you get here are jobless losers given the title of MVP to buy their loyalty who will help you, or try to help you. It is up to you to act on this because there is no certainly anything is going to work. They are jobless so you get the idea!!.
