Hi all - sorry, I've had no time to add more features to WebView, and it looks like that's not going to change in the near future (swamped by other projects and work) - I've not even been able to work on the simple MMF iOS app that was my whole reason for making WebView in the first place!
The good news is FVivolo has worked on a web object for Windows (for both MMF standard and developer) that has more features than this extension, and with the idea of making it friendly for iOS-porting, so hopefully some other iOS developer might be able to pick up on that long before I can return to WebView.
