Good to know that it’s in beta, and that a modern UX (New Version) is in development for that.
Is there any chance of a semi-public beta (like Tinderbox’s recent one) where users can buy access and try out the app? (Not sure how that would translate into a free license, like Tinderbox for Mac, but I suspect that there’s many who would be willing to pay for just the ability to test (and happily buy a new copy afterwards in the iOS App Store).)
