Just what I want starts out giving the user everything, but after a couple of weeks of training, the UI adapts to how the user interacts with it. ... "Didn’t I have a search field before?" The short answer is: yes. But who cares if you don’t use it anyway? Microsoft Office used to have a UI that would do this. It was always the very first setting I'd change, disabling the feature. And Microsoft eventually discovered that it caused more confusion than it solved: people remembered seeing a command somewhere, but couldn't relocate it because it had been hidden. Perhaps Microsoft's implementation could have been smarter, but I believe that they successfully demonstrated that this approach does not have merit.
