It would be nice to have a option for an audible feedback when we move the thumbscroll wheel on the MX3. I'm actually a little disappointed there aren't detents on it, but that's not something that can be added via software update. I just want the option for the PC to play a "click" noise whenever the assigned button press is sent - for instance, I use mine for right and left arrow keys on a web browser, but It's hard to know whether I've rotated enough for one or two clicks when I have to wait for a webpage to load. A simple, user-definable "click" sound would be a great solution for this.
