The biggest challenge and change is the customizable Toast Notification.
You can not change the sound it makes or even remove all the sound (default setting for it).
Btw you can change the icon by going there:
C:\Program Files\SoundSwitch\img and replacing the png by your picture (keep the same filename). This is an easter egg, not a voluntary feature.
