Replace javascripts "display: none" with class

I have a small feature request.
The module hides the fac-results by inserting a 'display:none' through javascript. This is a little bit problematic if you want to put some nice animation styling on it. Would it be possible to replace the inline styling with a class that hides the element?

You could make your own specific class, or re-use Drupal's '.hidden' class (which defaults to 'display:none').
That way, themers can easily override the CSS and create their own beautiful search results.

And if you're at it, the same could be done for the 'position: relative' inline style set on the form, so it can be easily overridden.
