Just posted a new article @ FileMaker Weetbicks entitled Swipe-Out. It's all about a technique for building native swipe-down gestures on FileMaker Go. In our demo/article we're using this to dismiss a menu which slides in from bottom of screen. By swiping down on the layout we can move the menu down and dismiss it as if we swiping it off screen. This is 100% native and works great.
