Oh, if you go the route of a custom view like Jens and I suggest, don't forget to implement Accessibility for it. You can probably just give a number indicating the level, but otherwise you might have to do whatever NSSlider does to expose itself to Accessibility. Or maybe you could just subclass NSSlider, replace all the tracking and drawing code, and that way get Accessibility for free.
