I'm not sure if this has already been done or has been requested but a RomUlation toolbar would be nice.
What would be nice about a RomUlation toolbar? It's already possible to search RomUlation from your browser using the opensearch box (one in the upper right corner) of IE7, Firefox, Safari and Opera. We can actually make some money with a toolbar, but we didn't think there'd be very much interest.
