Inspired by Karl's Xaml Power Toys, I've released the first part of the MoXAMLPowerToys at http://peteohanlon.wordpress.com/2008/09/16/more-moxaml/
It currently changes automatic properties into notification properties (for C# only), and it allows you to automatically comment/uncomment XAML code. New features will continue to be added, aided by its extensible Command architecture. The source is available for you to download and play with.
Deja View - The feeling you've seen this post before.
