Doug, I think you might like an awesome toggle widget someone here tipped me off with. I use it for the quickest possible setting changes for:
1. Wifi toggle
2. GPS toggle
3. Bluetooth toggle
4. Volume slider
5. Brightness slider
6. Landscape, Portrait, Auto-Rotate screen settings
You can tweak the look and functions of so many settings that sit as a widget on your screen. I have mine setting at the top of my screen. It sure beats going through multiple taps just to change different setting functions you may find your self needing quickly through out the day. This is one of my top 3 "must have apps" !
