Centering Text Label In Widget Title

Is there a way to center a widget title? I have tried using <center> and the close tag but that does not work.

By default, it appears to justify left.

As a side note, an enhancement for future releases might be the ability to label a widget and not display the label. Example, I use a lot of TEXT widgets to house an ad. I don;t want the name of the business to display over the widget, yet in the admin panel it is difficult to discern what widget is what.
