Ditto that, Erik.
The only thing from my point of view is that I'd like to see the confirmation message when you make a move either movable (so you could slide it out of the way and better see the board beneath it) or more transparent (so you could better see the board beneath it). But that's perhaps just me and is not a 'bug' but a 'feature'! But it has been a privilege to be a part of the 'ground floor' of a great app...
I'm guessing that the beta is winding down now, since you've submitted an official build to Apple. I'll keep an eye out for the official version, but I just wanted to thank you for allowing me to participate in the beta. It's a very nice app, and I'm proud to have helped test it. I'm also pleased to have had advance access.
If we find any further bugs, would you prefer for us to submit them via the usual bug channels now, instead of in forum posts here?
