Ok. That's nice to know.

And nice to see that there is people who realize the inevitable: The tweaks seldom makes you go any faster. You might feel like it but the stopwatch usually tells different. This is why I would like to concentrate to the basic UI and usability, at first, and later on add more customisation options, if necessary.
The way I see it, concentrating on designing and creating unified and efficent UI before actually adding any customisation options should make the UI better. (Consistency and standards) Random points rarely form clear picture. Customisation options could be added later on, if necessary.
And, of course, to make my point: "Ease of use is made by the absence of power" - is a myth. Both can be achieved, although it is not easy.
Also, one thing that must not be overlooked for is help system. Well written, clear, helps and documentation are one of the fundation stones of good UI. Not to mention good implementation of help system itself.
