In this version I’ve updated the formatting of the main page to use styles to help clean up the markup. I also fixed up several of the markup items to allow more natural layout to occur. For example number buttons are now styled:
I’ve also updated the [+] and [-] buttons to use the Windows Phone 7 Icon Pack for a better appearance. This icon pack has all the most common icons you’ll find in phone applications.
Finally, this version of the tools enables the ApplicationBar so you can place extra controls at the bottom of the page. I’ve added a “clear” button which zeros out the totals.
You can find the updated version of the sample source code here.
