Bare minimum to get it to compile

I did the bare minimum to get it to compile here. For the rest, going forward, we have to look at either using more new pages (e.g. About, groupDetail, groupItems, itemDetail) by copying and pasting what's there and modifying the data structures and parsing accordingly -- or ...

Look at doing it yourself without the shackles of Microsoft's approach. This guy makes a few good points: http://labs.vectorform.com/2012/07/motown-easy-javascript-apps-for-metro-part-1/ Though I haven't yet tried his code. I'll take a look at things tomorrow after 7 or so. Bug me via FB messenger if you like.

My point being, though, that this is just JavaScript at the end of the day, and you can write it like a webpage made for IE10 using Blend and then import it and package it as an app without having to start with their templates if it makes life easier. Then go feature by feature. Perhaps following the walkthrough where they make Contoso Recipies will help.

That said, if you want me to do things for you, I really don't mind, but I have to know what the screens should look like and what you want on each! :-) Use Sketchflow or napkin sketches that you scan in, or something, but I can't know what you want if you don't tell me ;-)
