All the settings menus are a nightmare of lists upon lists and each app has a completely random layout for it's menu-ing, often with links to external sites, for what could be set locally.
It is geniunely confusing to try and understand the designers intent. I can never tell if I missed a setting, or if it was never meant to exist in this menu at all.
The amount of times I've had to Google how to change basic settings is way too high, even for Games where the experience is half the ticket value.
CS2 has a settings menu with text buttons at the top (like a tab) that drag you down to an arbitrary point in a long list of settings. There is no tabs, it's impossible to mentally separate what the text button represents mentally, from every other option, because they all point to the same page anyway. Why bother with the buttons?
The semantic meaning of concepts don't relate to each other and are not structured accordingly. It is waaay too unnecessarily difficult to navigate around computing.
I miss Macromedia Flash's UI. I didn't use the program much, but it was so simple and easy to use.
One my biggest drives for privacy and self made solutions, is to get away from the experience and knowledge pollution we've been seeing lately.
