Changing the icon

As you've noticed there is no icon for the entry on the settings panel. This is easy to change. The file entry.plist (inside the /sliderchangerprefs/ directory) contains an entry called icon = SliderChangerPrefs.png.

Now go to the folder /sliderchangerprefs/resources/ and put a 58x58 file here, and name it SliderChangerPrefs@2x.png. For non-retina devices you should also put a 29x29 file here with the same name, removing the @2x part.
