Expanding the WordPress Quick Edit Sections


Does anyone know how to make it so you can expand the category areas in the post quick edit section in the wp admin?

My client has a large category structure as we have used it for a product category tree. They have about 50 categories with sub categories and want to be easily able to see all of the categories in the quick edit area so they can add products into the correct category.

If anyone knows of a quick piece of code that will allow this area to be expandable (ie you can pull the area bigger), that would be appreciated
