CDex should have a cleaner interface imho. Cut all the options most users never use and put it in an 'advanced' window. I created a mockup of that. See attachment. You don't really need much more than that as a normal user. Set the defaults in a sane way and remove evertyhing which doesn't make sense to a normal user. I know some people rip to WAV, most do not. So move that functionality to anotrher window. In the mockup the button in the lower right corner gives access to all advanced stuff. Do you like it?
