Codea is great! Thanks for such a lovely tool (at such a reasonable price).
Of course, the one thing missing is the access to the face detection API (eg like this: http://maniacdev.com/2011/11/tutorial-easy-face-detection-with-core-image-in-ios-5/ )
I know most people want this, but are too afraid to ask here. On behalf of this silent majority, we demand this API integrating into the next release!
