This new widget inherits from the standard reference widget so you can use all it's properties. For now, the addable feature has not been implemented/activated but that's not difficult. The only reason I haven't so far is that I have my doubts for it's usefulness. But of course, I can be wrong ;-)

When you use this widget, there are two buttons presented for each widget. One that opens a popup-window that let's you do the search/browsing and one that let's you clear the reference or selected references (will be in effect after the form's Save).

The popop window basically consists of two parts. The top half is a search form and the bottom half is the browser/search results part. Both parts can be turned off or on using the widget's properties.
