Hi all. 

I would like to see a propertyChanged message implemented that gets sent to any object when any of it's properties change. There could even be two messages, one for built-in properies and another for custom properties. 

Imagine being able to change the font or size of a particular object, and then having all the other objects that "subscribed" to that object's font or size property ALSO have their fonts change. It would then be possible to build a kind of Object Oriented environment. What say you?
