I will admit I have not read every post in this thread.
I have a zany idea.
How about in the iPad options there being a list of say 3 or 4 different functions that switch can do.
And let the user decide (based on their needs) what the switch does.
No one setting will be right for everyone.
How about we push for that as an idea?
Give the user a choice.
YAY for Piggie! Yes, let's push for that idea!
