Hi Wim,

I'd would be nice if the styling of the elements were split up into two (or maybe even three) CSS files. One for functionality and one for styling. Currently, the CSS that come with the module defines color of links, table backgrounds and font-sizes, which which might not necessarily match the styling of the current theme.

I now have to remove your CSS file and figure out what CSS I need to move over to my theme, which is a lot of work.

See how it is done in core: http://drupal.org/node/1216976#cleanupcss
