Was wondering how to go about implementing a plugin that will allow a user to load more then one content type when clicking on a certain filter. Say we have three different types of video-based content types such as Member Video, Professional Video and Non-member Video and we also have other content types such as Photos and Blogs. So by default the content type filter will show 5 links (Member Video, Professional Video, Non-member Video, Photos and Blogs). What if we wanted to have one link, lets name is "Video" that would filter the results to the three video content types. Is this possible, if so, which plugin would be a good start?

Thanks,
