pull down to refresh

Heh, exactly. I've had a couple of these for a while, and when I saw the matching model I finally pulled the trigger and managed to burn, erase, burn, save, download, erase, burn until I got it to work.
I'd like to make a couple of changes, like the background reflecting the usual green/red signalling, but there's a bit to learn before I can confidently do more than stare in awe at this little box with its wi-fi and capability.
Color signaling is a great idea. If you come across any free API which provides price changes, please share.
