When I insert multiple instances of widget in a particular sidebar, they all appear by default collapsed and with the same title. E.g.:
In this case, the user can upload a different pic to each widget, and reorder them as they want. It's not very user friendly having to click to open each one to see if its the one that they want to remove/edit/change of place.
With the form() method of the widget we can change whatever is shown once opened, but the "<div class="widget-title">" and its corresponding "<h4>" are out of bounds.
Is there any filter or action that allows to edit what happens there and insert some instance specific information? E.g.: "Graphic Ad: Foobar".
