For example: Dragging a RF component should result in a intelligent fill in of choices. ie give you a 2*4 table when dragging in a Rich Faces table. google table with a few typical fields filled in. etc etc html fields ( name, target, etc) as typical defaults.

As I see this issue, we should implement possibility to set templates for components, like it done for java editor in eclipse preferences. (Preferences->Java->Editor-->Templates) for example.
