As a mac user, thank you so much for this wonderful app! I was wondering if you are planning to open source it? I am a bit leary to enter my API credentials since they could be sent by the software anywhere. Please don't take this the wrong way

It is just that we keep 5 figures on our mtgox account at all times

I know it's not much, but I promise it isn't sending anything anywhere! For more solid proof, if you have software like
Little Snitch (which I love), you can verify 100% that the only thing this app connects to is socketio.mtgox.com, which is MtGox's streaming API interface.
Also, for a bit more security the page I link to is on my personal site, which includes my full name, and my actual address is in the whois information for the domain. I would never do anything shady like that online, especially when connecting it to my real identity!
