Safe shutdown when turned off #6

Looks like when I flip the juicebox to Off, it's just a hard power disconnect.. makes sense. But, most of the time that is NOT a good idea to hard shutdown. Screws up the SD card and what not. Any way to do a safe shutdown WITHOUT waiting until the battery goes to 3.2v?

I made my own:

You could probably solder a little switch between the collector and emitter of transistor Q1 (maybe with a little 300R resistor to be sure). That way, the shutdown itself would be handled by the same code as the low power event.
