Add CSS class to widget

I use both BlackStudiotinyMCE widget and the Enhanced Text Widget plugin. The BlackStudio Visual Editor widget is far better for end user use and for adding images.
The Enhanced Text Widget is needed where I want to position the widget on the page or add specific formatting, such as in a header area. It has a CSS Classes field which adds a CSS class to the widget container.
Can you please consider adding a CSS Class field that allows addition of a class to the widget container so that the widget can be styled?
Thanks
