ECO1: Save cracked out hippies from accidentally darkwadding themselves
There is a software feature called "ship mode" which is a one-way door on the production doors: once you hit it, the system will power off, and will not power on again until you plug it into a USB port.
I could see this being a problem for some people in the deep playa.
Add a bypass switch + diode to jump-start the board into life again if the battery has a high enough voltage (needs to be about 50% capacity or above to jump-start itself).
This feature is a bad idea in Default because it represents a small, but real, safety risk. You're supposed to isolate the battery entirely from the system during "ship mode" to prevent any accidents. The bypass switch gives the remote possibility that a system can power itself on while shipping, leading to a deep discharge of the battery which is a potentially hazardous condition.
But, safety third!

| added | SW10B 5x5mm 1.6mm tall PB |
UPDATE: decided to cancel this ECO. UI changes should make it hard to darkwad yourself.
ECO2: Adjust gain on sound
R11S is adjusted to 47k to make the microphone a little more sensitive.
