Now that I don't need to try and keep this a big surprise, if anyone is interested in being added to TestFlight and helping test out new features and the like, drop me an email. Make sure you let me know which email address you're using for TestFlight so I can add you.
We have an iPhone version 1.1 update just about ready to test, along with a new Desktop version. Some nice improvements and new features but also some pretty major changes behind the scenes to facilitate them. The more testing for this update the better!
