New Post: Win RT Settings Flyout - Windows 8.1

I've scoured the internet and found very little guidance on the settings flyout for 8.1. It does appear different than the Win 8 implementation and what little I could find on Win 8 doesn't seem to apply. I'd appreciate any help with the general calling of the flyout, what ViewSettings I can apply, such as width, etc. (or guidance on how I could find this out) and how to override the back arrow functionality so that it doesn't take me back to the Win 8.1 Settings Panel, but rather closes the currently opened panel.
What I have so far doesn't work with View Settings and I have a feeling I'm doing this all wrong.

var viewSettings = new Dictionary<string, object>();
viewSettings.Add("Width", 500);
windowsManager.ShowSettingsFlyout(new PassageListEditViewModel(navService, eventAggregator),"Hello", viewSettings);

Thanks for any help
