Thanks for the input.
If you say it like that there are little chances of changing anything. The only way we can improve is to know why something does not work. Only when we know the reasons can we start to react properly. So, please do let us know what does not work.
Just because it is about the way something looks does not mean that we cannot have a structure discussion about it.
Please note that I am not saying that the white theme is the ultimate design. It is not. But, to find other means of expressions we have to leave the classic one and build simple things in simple ways. The white theme has a small amount of visual variables which goes hand in hand with the philosophy of Pharo. This is something to nurture, not to push away. If something does not work for a reason then we look at it. For example, when the scrolling did not work, we changed the color. I want to spend the energy in doing that, but I need your input.
Just for the record, I am doing similar usability experiments with people that do not know Pharo upfront, and they seem to have no problem finding their way. So, it is not quite as random as it might appear.
