I only use it for bringing up SmartTag on things like GridView, DetailsView, and DataSource rather than generating all the tedious BoundField and Template controls by hand. Usually, this is only the first time it's configured. Afterwards I generally edit the mark up by hand because I convert some BoundFields into my own BoundField-derived class that supports different types of validation.
