modifying basic and widget titles

This plug in is great!

I am having two little issues though hope you can help:

Is it possible to add a text and a title to a simple form that is inserted into a page using [wp_email_capture_form]
Is it possible to remove the title from the form that is inserted in a widget without getting the default message?

Thanks
