Sometimes we want that an additional element is rendered inside the title bar field (an image/icon, a progress indicator, ...) and to respect this demand, we have introduced titleSupplement. The names seems to confuse a lot of people, so maybe we have to change it to a more catchy one.
Good point. Should be changed.
Probably this property will be removed. We don't need it any more, because it is bound to the dialog type now, if the close button should be rendered or not.

This can be achieved with setting the displayIn property to the page.
> -two popups at the same time -> no double dimming
This should be avoidable with a properly set displayIn, too - but I have to check this yet.
Thx for your comment.
