Optional Label with a Text Input

For a Text Input, it would be nice to be able to optionally provide a Label as a property, or as a comma list, like "User Name,John Doe" and that would be interpreted as a Label of User Name followed by a Text Input field populated with John Doe. In addition, a property to tell the orientation of the label to the Text Input field would be nice. (Label above the Input Box vs. Label to the Left)
