, 12 September 2012→As a front-end developer, I need the app to tell me when a layer has received focus so that I can check for updates and refresh data if necessary.

'' Focus isn't quite the same as active/visible. On the desktop, focus doesn't happen until an element in the window receives focus. I'm not sure how that plays out on touch devices. I think we want visibility'' | |||
''There is an actual API for this: [http://dvcs.w3.org/hg/webperf/raw-file/tip/specs/PageVisibility/Overview.html PageVisibility] but we would have to investigate browser support. As I understand it, our "layers" are going to be window object in UiWebViews or their equivalent, so this seems like the right place to start. I would rather polyfill this though than invent our own.'' | |||
