Couldn't one just add a timer that pretends to click the update gps button every n seconds/minutes? I for one don't even want a daemon for this, it's fine to just start the program and click the auto-update button and when i don't want to auto-update anymore, I'd just close the program. I'd figure that clicking the auto-update could launch some timer/sleep thread that would fire some updateGpsButtonClicked function when done.
