Very cool and very fast. One small request is that (on the iPhone) the app's window sizes to the viewport and so you can't scroll the address bar up out of view

Very cool and very fast. One small request is that (on the iPhone) the app's window sizes to the viewport and so you can't scroll the address bar up out of view. On < iPhone5 this means that with both the app's nav bar and the browser's nav bar in play there's very little real estate left. However... having added it as a desktop icon it's phenomenal (no browser chrome). Very impressed. Would be great if it told you at the start that this was the outcome from adding it :)
