I had not used the document outline (ctrl Alt T) that much in 2002. It didn't work every time or didn' feel right. In 2003 the tool works like a marvel. It really gets interesting when you have a control with templates, like a datagrid or datalist, and change to HTML view. All html controls appear in the tree and the property window follows the control / tag selected. It's an overview you don't want to miss. What would be nice if you could expand and collapse the html tags in the html editor. Just like IE does with xml in the browser. Next version ?
On the coming Professional Developer Conference MS will present the things to come (Whidbey) to the developers community. I just can't wait.
